I chronographed my new bow last week and it was disappointing to say the least. It shot at 235fps with 65#. However, the speed is due in large part to the heavy 340 S/T axis arrows i am shooting. I then shot a 410 a buddy had and it shot at 255. My bow only goes to 70# max. I was looking for any suggestions on increasing my fps so that i can stick with the 340's (besides cranking it up to 70#'s which is what im going to do. Will changing over to blazer's help anything with speed?
