Thanks for the links guys, from the results I saw I think maybe I will stick with the muzzy's until after my first kill and then do a comparison test with the spitfires. As 5shot said his test do not emulate the taking of game. The one thing I did like about what 5 shot said about the spitfires is they fly just like field tips, which to me is a big plus.
