Thanks, Gang. I'm kind of a perfectionist when it comes to finding the happy medium between arrow flight, speed, and penetration. I've gone light, heavy and in between. 2-blade, 3-blade, large heads, compact heads. I'm thinking of splurging and going with a combination of Beman MFX Classic 400 with 300 Xtreem broadheads with right wing Gateway Rayzr feathers. That should put me over 600 grains and over 19% FOC. Hopefully my 52lb'er can throw it over 180 fps. Then all I'll have to worry about is arrow flight.
