I've bowfished for years using a 40-45# recurve and releasing with my fingers.
It wasn't until the last few years when I started shooting fish with the compound that I use for deer that I had problems.

I like using my compound for fish because of the extra power and hold time, but I've got a left tear that will cut the paper in two! This is especially bad for bowfishing since the ranges are so short that the arrow does not have any time to recover and when it hits the water while it's pointing to the right, it just changes direction and I'll hit somewhere to the right of where I was aiming. The deeper the fish is, the worse it is. Until I find a fix, I'll just be taking surface shots and compensating for the different point of impact. That's easy, but I want a real solution.

Does anybody know any tricks on how to get fish arrows to perform differently?
Are they all the same spine? Could I play with the arrow length to get what I want?
