These are the things I pay attention when scouting an area pre-season.
I use a modest sized 14x14 Beckel TT tipi w/ the horses and if we have a tree pole we cut a few years back that we go hide & retrieve each year. It's much stiffer than the sectioned alum pole & allows for a tighter pitch, and we left a few of the limbs 3-4" long to hang clothes off of, as well as the lantern, etc.
My advise, get a cheap $20-30 set of trekking poles that are adjustable and go scout it. Or cut a couple walking sticks on the way in and then finish cut them once you get onsite & go to pitch the Mountainsmith.
I will say this.... I have the Mountainsmith LT as well and I usually, at some point, end up adjusting the poles a little longer to tighten up the pitch. Or I end up moving a pole to make more room for me. Personally I'd want adj poles, just less hassles when you want to make changes.
But yes you can cut sticks/poles on site, but they may not be perfect and you might have to resort to shimming them up w/ a flat rock to tighten pitch. I'd cut them a little long, say 3", and start with pitch that has the poles leaned/canted off at the bottom. And as the fabric relaxes you can straighten the poles up to tighten pitch.
Hope this help put a couple thoughts in your head.
