What are you shooting?

Have been in the market for a fishing bow but have yet to make the plunge.
Local Cabelas (KC) has:
AMS Swampthing Tournament
PSE Discovery
Vortex H20
So these are the only ones I've actually been able to get my hands on and look at.

Not looking to hunt alligators but rather Gar and Asian Carp in/around Guntersville Lake, AL
What are you all shooting and do you have any recommendations? Anything in particular I should look for / stay away from?

Thanks.
