You seem to know your stuff .The animals we all hunt need to be considered to .I'm all about creating as much conetic energy as i can with my bow set up ,which is hard with a 27 inch draw and poundage at57.I don't want to cut down any more speed than i have to. 20 yrds is not a far shot for me at a deer and some times i over look that .Bows now days are reaching speeds up to 320 fps . My bow did feel less vibration with heaver tipped field points and arrows.But for the 3D at 45 plus yards i like a flater trajectory.Still carbons are my way to go and there prices are desending.
I hope old guy gets what he is looking for.
