I am pretty sure the gold tips are 5575's which have a .400 spine. The actual arrow length w/o the tip is 26 1/2". With broadhead, inserts, nock and vanes, I am probably around a 320 gr arrow. I chrono'd the bow with 80 gr field tips shortlyshortly after I bought it and it was in thelow 280's if I remember correctly. I am in my late forties and CRS( Can't Remember Crap)syndrome seems to be happening on a regular basis. I have since gone to Blazer vanes and a drop rest, so it may be a tad faster. I am considering going to a 100 or 125 gr broadhead. I will verify this infowhen I get home from work today and repost. Thanks for all of your responses. I am on the black powder part of this site quite a bit. This is truley an awesome site!! Thanks again.
