I'd go with the mtn lights. Pretty bomb proof and I like them better then the leather on the Alaskans.
I'm just the opposite. Only a 4 oz difference between the two and synthetic uppers waterproof treated are still nowhere near as waterproof as leather uppers waterproof treated. But to each their own. If I lived in a drier climate I might opt for the Mnt Lites for me in Alaska the Alaskans are ironically my choice having used both.
As for the thread:
New binos: Going from Zeiss 10X32 Victories to 12X50 Razor HDs from Vortex....might not even be an upgrade just trying something else. (weight savings=+9 oz)
New pack: Gonna give the Bikini/Highcamp setup a whirl this year. If it doesn't work out I can always revert to the Duplex/8500 setup which I know works like a champ for me.

However going from a 7 pound pack to one that is 4.5 pounds will be very nice. (Weight savings=-2.5 pounds)
Also got 850 down hooded jacket and pants to use this year on our summer hiking trips and what not. Saves Becca and I each 1.5pounds with this and we gain an insulated hood. However for $300 apiece to upgrade to 850 jackets and pants it was a spendy 3 pounds we are saving. (Weight Savings=-3 pounds)
A zpacks hexamid solo plus. Comes in at 12 oz with enough stakes to guy otu every point and all guylines installed. Compared to roughly 30 oz for the megatarp with all the guylines and stakes for everything we are saving another 1.5 pounds there. (Weight savings=-1.5 pounds)
So should be roughly 6.5 pounds lighter between Becca and I going in, which is always a welcomed thing especially being that 5 pounds of it is coming off my pack
Other than that the rest of it is boringly the same....
