Am new to this site. Just got back to bowhunting since retiring. Have a Ross 334 bow set-up, used to shoot the old 50% let off bows. I enjoy building my own arrows and have done so with Eastons St. Epics. Took two deer this year and am happy with my equipment, but it seems you can always find something to tinker with in bowhunting. Am presently looking at some Carbon Tech arrrows for more speed(Cheeta's). They seem to pack the same punch as my set-up now but are 30-35fps faster. Are they durable and what are the weights of nocks and inserts? Enjoy reading everyones opinions.
