Finch,
I saw your post a while back, and also saw that you were getting excellent advice. I have a couple thoughts to share, apologies for any duplication, but there are so many replies now that I don't have time to dig through all of them to see if anyone else has already shared similar thoughts...
BATTERY UNIFORMITY- Make sure electronic devices for all hunters use the same style of battery whenever possible - i.e. AA so you don't have to carry many battery types and can share spares if needed.
RADIOS REDUCE ANXIETY- The GMU you plan to hunt has many miles with no cell reception, even on ridge tops or in small towns. NONE. I know, I have a couple friends that live around there. Intentionally or not, you WILL get separated from your hunting partner(s) at some point and you will all be wearing camo. Now what? Whistle or yell and ruin your hunt for an hour or more, go back to camp and wait? Get a couple 36 mile blister-pack radios from REI or Ebay and make sure they are waterproof (they won't transmit anywhere near 36 miles in the woods, more like a mile or three at best). They also will not transmit through a mountain into a drainage on the other side. However, they will save your a** and keep anxiety low. They will also let you split up when scouting or tracking and still be able to find each other (Before anyone out there chimes in and plays "attorney", be forewarned that you can't use them to "hunt" and get advantage over game in many areas). That said, you'd be foolish not to get them if w/in your budget. Also get ear-buds with PTT (Push-to-talk microphones), these can pick up the slightest whisper as long as the mic is right at your mouth and your buddy will hear you well. Be certain to get the radios fully programmed and checked before heading out, many models are difficult to program in order to eliminate beeps, etc. Also, be sure to understand that certain channels allow the radios to operate at higher power levels than others and thus offer better range. Stash the radios in a side pocket on your backpack and run the PTT wire so it won't snag on underbrush, but still allow you to dump your pack. Batteries will easily last a couple 2-3 day or more if the radios are off while you're near each other. Get the units that use AA batteries, not rechargeable packs.
PANTS- get some lightweight zip-off convertible pants, make sure they take a belt. Early season can be very warm, even if not warm, climbing w/a pack will heat you up. KEY POINT- when you're hot, zip off the lowers, don't take them off, just roll the lowers down toward your ankles and the tuck the rolled up lower leg into the upper part of your socks. Not a fashionista statement for sure, but very efficient. When you're stopped and cold, pull them up and zip 'em.
BELT- thin belt that won't put a pressure point under your backpack belt. I use a nylon webbing belt.
KNEEPADS- Are a must. You can flop down on your knees any time, anywhere and not worry about hurting your knees. Especially handy when spontaneously praying for that big bull to come back..! All joking aside, some folks like pads integrated in their pants, I don't. I like pads I can use with shorts or any pant I choose. I really like Black Diamond TeleKneesis pads. Made for telemark skiing, they are light weight and articulate well. When you don't need them, just loosen them, let them slide down on your shins. Tighten the lower strap a little so it sits just at your boot top, then snug the upper strap at your calf. Need them? Pull them up and snug em up.
YOU ARE HUNTING TO KILL, NOT PLAY- never, ever make a bugle or cow call or go to go the creek for water without your bow and release. I once playfully threw out a call at a bull that was 500 yards away and almost 1,000 ft below me in elevation, thinking I would get his attention. I did. He was on me and then past me before I could move into any sort of a shooting position and get my bow off the back of my pack. Another time I went to pump water from a creek, left my bow at camp. Let's just say I'll never do it again.
MAPPING- I did see where others suggested MyTopo. Great tip. I have had them print me several 2'x3' maps for various area I've hunted. The quality is super. They use waterproof ink and Tyvek paper, so the maps are bomb proof. Mytopo also has a subscription service called MapPass for $30 or so/year that lets you print from your own printer or any other printer. The only drawback is that the service limits you to printing on 8.5x11 or 11x17 paper. If you subscribe, I suggest doing a quick search on EBay for Tyvek printer paper and buying a small box of about 50-100 sheets for $40 or so. Then you can print all the photos and topos you want, cheaply. Lazer printer printers use toner and toner is waterproof. Ink jet printers often are not.
HILL MAP at HillMap.com is another great and FREE mapping/aerial photo site. Printing is a bit awkward and you are limited to printing on 8.5x11 paper I believe. Best part of this site is that it allows you to use various overlays on top of a topo. One of those is extremely slick! It was designed as an avalanche tool, it takes a topo, then shades it in different colors depending on the steepness of grade. Makes it simple to quickly assess entire mountains for best places to travel, squeeze zones, etc.
Hill map also allows you to create custom routes on your computer and download, then pre-load them into your GPS.
WEATHER- if you have a Sat Phone- have one two friends at home or work check the on-line weather for you daily. Have them write down the week long forecast day by day and text it to you if your sat phone takes texts. Hi temp/low temp, % chance of rain and if T-storms are expected. If no texting on your sat phone, then call them from it when you're on a ridge and have them give you the scoop. Waste no time on small talk. Sat phone minutes are expensive.
TREKKING POLES RULE! I used to think they were for losers. Not. Used properly, they will increase your climbing efficiency by 10+% and take a huge load off when descending steep terrain under load. Add that up over the course of your hunt. Set them a little long and lean into them like doing an ab crunch when climbing steep stuff.
COMPASS DECLINATION- for proper declination adjustment, go here and input a nearby zip code
http://www.ngdc.noaa.gov/geomag-web/#declination (NOAA- your tax dollars at work!)
BUTCHER- line one up now and know his address/contact info and hours.
SOCKS- I love SmartWool PhD medium weights hikers, crew height. If need be, you can get 2-3 days out them before swapping into fresh ones (assuming they don't get wet). I have never had a blister with these.
Many thanks to all those who have posted on this site and other sites where I've learned so much. I hope this helps!
Good luck!
