I'm sure I'm not the first to tell you this but you should be able to get just about any fixed blade to fly with your FP's. It takes a little work but can be done. It is so much more rewarding once you get your FP's and BH's hitting the same spot.

I've always used the regular Muzzy 4-blade. Couple seasons ago I used the same BH on 2 deer and a turkey. Even then, it was still fine to shoot. I just made sure it was sharpened well.
