I'm 6ft 5...250...I have 2-APIs...One is the Grand Slam Supreme...One is the Magnum...They are very comfortable...I can actually nap in them while hunting...

There are two advantages of an API over a Summit that I have found...
1) The APIs have a padded shooting rail that can adjusted up and down....Hunting over bean fields or cutovers or power lines, where shots can be longer, this is a huge advantage....It is almost like shooting from a bench...

2) The locking pins, that go through the chain can be removed and replaced with 4 long shank locks...For someone to steal it, they either have to cut the climbing chain, or the frame of the stand...I usually bring my stand out with me, but if I plan to hunt the same area the next morning, I can leave my stand in the tree...
