Now, now JRW....
Washington Hunter, if you already have the recurve, then by all means use it.
A recurve has several advantages over compounds in bowfishing. They are lighter (usually), faster to shoot (usually), and you don't have to come to full draw (nice when the fish are really close or in log jams).
Me, I shoot a 17 year old compound that weighs 7lbs. Why? Because it's more challenging...
(okay, actually I'm too cheap to get a better bow)
