I use an Ameristep Penthouse. It does mess with my depth perception until I get used to it, but I have killed rabbits, deer, a fox, a squirrel, etc. from it. I've shot 2 blades, 3 blades, and blunts with no noticeable affect to accuracy, with the longest shot being about 23 yds (the fox). Friends have used it and made kills out to 26 yds or so--that longest shot was on a whitetail, and the young lady that made it was pulling maybe 32# and killed it with a 2-blade Ace.
No complaints here.
