So if I drop 15 lbs, the Guido's Web will feel like nothing. Maybe I will just sell the rest of these saddles, pay for a liposuction and hunt from my weight-free Web!
I think if you are prepping trees and can get a small, cheap treestand base it would make a fine platform. If you are up 30 feet in the crotch of a tree with some back cover, and the stand is pre-hung, you are adding all the comfort and avoiding many of the negatives folks mention above.
I agree that if you are run and gun, carrying steps, bridge, tether, etc along with a full tree stand base, you might as well just get a climber. But if you have the right spot and the right tree, I think there is a place for it.
