I have bowfished for over 40 years and I like dedicated bows for the occasion. Hot and heavy action on big fish and gators is brutal on our bows. While guiding bow fishermen, I have used every conceivable type of bow out there and we have come to this conclusion, go with a light weight (carry weight), short bow. The short bow is particularly important if you ever shoot from a boat with a shooting rail and when you are shoulder to shoulder in a boat. The draw back to a heavy bow becomes apparent after holding the bow for several hours.
If I had bow building skills, I think I would opt for a 50" bow that pulled 45 pounds at my draw. I would include both front and side bushings for both types of reels.
