Personally, I have always been of the opinion that you should let your tip weight compliment your arrow and your bow. I shoot a 29.5" 340 ST Axis with a 125 gr tip. I shoot it at 61#s off a HCA Iron Mace, which has a very hard two cam system (same as a bowtech). When I was shooting 400s with 100gr tips, I was getting a weak arrow reaction. When I went to 340s with 100gr tips, it was just a bit stiff. Putting those 125s on the front made all the difference in the world. Yes the FOC went up, but more importantly those arrows fly like a dream. 450grs at 280 from a 61# bow. I think the arrow will make it through.

My girlfriend is shooting a 42# Hoyt Trykon. I forget exactly what her arrow weight is, but its fairly light, mostly just because thats what was available to us. We keep her shots inside 25 yards (though she has yet to get a shot opportunity). Her arrows I think weight something like 340gr, and they are going at around 220fps. I have her set up with 100gr Strikers. Her arrows fly very well. I've been working with her to up her poundage just a bit... I'd like to get her shooting above 45#s.... 50 if possible.
