Joe, you ever think of going with bamboo/tomato stakes. In my limited experience I find them very forgiving of spine weight.
Bow fishing is a blasted--the most fun you can have with your clothes on. Carp should be moving out of the rivers and up into the streams about now. I have a FG fish arrow that I've never tried out of my primitive bows. That a good idea, I would recommend taking the barb out.
