RE: Oneida for bowfishing
They are a nice bow and are nice pullers to go all day.. I don't know why people choose them for bowfishing, I chose mine for deer hunting.
If I were to be buying a new bow for bowfishing I would look at getting the Oneida Osprey in the 35/55 limbs. It is basically made for fishing especially if you get the stainless steel version of it. Everything on it is weather resistant and reacts well to wet conditions. Oneida's have huge adjustability so you basically choose a variation in draw lenghts. I would probably go with the Short if I were you but that is just me. It adjusts from 27-30 inches with a 7.5 inch brace. These bows are great for finger shooting and instinctive shooting, a lot of finger shooting archers around here use them so this probably plays into the bow fishing thing.
There are probably one or two used ones laying around at archery stores or on e-bay that would get the job done for you. I love my Oneidas but mine are a bit much for bowfishing carp... One of these days I will buy a 35/55 for fishing.
