The silverhawkshould be a good bow to use. Ibought one recently to try for bowfishing. I just put a Bear Weather Reston it and shoot "instinctively". I also have a PSE Kingfisher T/D Recurve for bowfishing.

I'd start off with an inexpensive outfit and see how you like it. You can always upgrade to a more expensive reel later and then you will have the cheap one as a spare. An example isshown at:

Or if you have an old spincast reel (heavy duty) you can buy a reel seat that screws in the stabilizer hole.

The only drawback to the spincast type reel is you have to remember to release the line before you shoot, or things can gettoo exciting.
A couple fish arrows with the safety slides or a cabling system are basic necessities to have along.
If I'm right about your location you would be north of Cinci. Not familiar with that area, but some of the big lakes would be a good starting point. Look at the inlet areas of the lakes for largeareas of shallow weedy water for carp.
