I think it all depends on your draw length, bow riser and arrow rest - and/or a combination of those.

I have a 30" draw and my Easton aluminum arrows are cut to 30 1/2". The field tips and broadheadscome close to the tip of the "prongs" of my TM Hunter rest, but with 1/2" ofarrow length left,they don't fall off.
