get the SUMMIT 180 MAX .its better than the TITAN because you can face the tree.new 180 MAX FOR 2010 HAS THE titan FLOOR.FACING TREE WHEN LEAVES COME OFF HIDES YOU .it also gives you a nice gun rest.like i use muzzleloader and rest it against the tree.
TITAN would be my next pick.no other stands are as comfortable to sit in than SUMMITS.
if light weight is most important thing for you then go with LW.but expect to pay 400 dollars vrs SUMMIT titan on sale tyd for 274.
summit vipers are no.1 seller BUT there top section is too tight for me with heavy hunting clothes on.
