Last year I was shooting a Mathews helim with 28" draw 60# using a carbon express pile driver extremes a 56 gr insert with 125 gr tip cut to 27" they flew great out to 110 yards 350 spine
I draw 66# 28" with a 28.5" beman ics hunter patriot 340. I went with 340 because I don't mind shooting 70, but I back down as low as possible to still have the spine correct and tuned properly. Plus, my bow is a pretty harsh cam and a stiffer arrow is recommended.
