FWW its like Tony said find what you feel best with and make a good shot. I have used Muzzy,Satil. Mags and now use the spitfire all have been 100 grain and all have worked for me. I hunt almost every day of the season in Mass. or N.Y. or R.I. I took 3 deer with the bow this year and thats how many I shot at. Last year I took 3 with the bow and same thing thats how many I shot at. Best year ever was 4 years ago 5 with the bow and that was the first year I started with the spitfires. I have not shot at a deer with the spitfires that I did not recover! I can not say the same from my fixed blade days

but then as the years have gone by I find my self passing up shots I would have taken back years ago so it just may be I am only taking better shots. But I can say this I don't ever think about changing to another blade theses days and that has to count for something. Shot placement is more important than anything else combined. And for me the spitfires fly better than any fixed blade I used so that equils better shot placement. Four years not one deer lost. Good luck
