I'm in favor of recommending older bows myself.
If youdo go with one, consider changing the bowstring, or at least carrying a spare. They get wet all the time, and are abused on every outing. Longer bows will crowd up the deck of a boat pretty quickly, but you can use anylength when you are just wading or stalking from shore.

For reels, I like the AMS Retriever for regular everyday recreational bowfishing because it is so foolproof and reliable, but when you are competing to see who can land the most fish in a given time, I have togive the nodto the spincast for its retrieval speed and fish-fighting advantages.

Most bowfishermen end up with at least one of both setups eventually.
Ther's more than one way tospear a carp.
