Being 6'5" I chose the new nanook xl based on its size. Biggest and lightest two man flip available in that price range. I'm the same way jerryfising, I can't stand still too long in one spot with no action, I move too much to be anchored down.
The wife was pretty much the biggest influence on me buying a shelter. She wanted one more than I did...I don't really care. I'm the knucklehead out on the ice when it's 15 degrees out with no gloves or beanie... heck the one time I forgot my pac boots and just wore my asics running shoes on the ice...didnt bother me, lol
