Fish,, welcome and awesome bow... I shoot a Pittsley and for arrows theres many but I opt for the heritage mainly for price (Big Jim) and the overall the grain weight.
I never liked goldtips personally,,, you should try the Heritage 250's have them cut at least an inch longer than your full draw because nothing is worse than drawing back your first broadhead only to hit the back of the riser with the broadhead (my fathers version of the draw check)
first try stock inserts and with different weight heads to find the right spine, I think some folks sell test shafts and also field point test kits,, don't have them fletched just shoot them bare shaft out to 10yds while holding the bow perfectly verticle and tell us what they are doing and we'll get you set up perfect..
