I had a PSAII, 60" long and 56#@28". I shot a 29" to bop .400 easton carbon with a 100 gr. brass insert and could use either a 150 gr. or 200 gr. point. I would suggest going with a 29.5" .400 spine carbon (a Gold Tip 55/75 is a .400) and a total point weight of 200 to 250 grains, using either a standard insert and heavy field points or a 50 or 100 gr. brass insert with some different weight field points (125, 150, 175, 200, 250). I think some of the sponsors here offer field point "test packs" with several different weight points. On my old PSAII, I got excellent bare shaft arrow flight with my above mentioned set up. I, like some others here, have found that some of the charts tend to over spine. The charts are a good starting point, but YOU testing YOUR bow with some different combos is the only way to get your bow dialed in! Good luck and let us know what works for you! Mike
