Thanks for the responses. I think I may have figured it out. The bow is not noisy.The arrows shoot perfect through paper and group excellent.The helical is roughly the same ,I really can't visibly see a difference. But the quality of the fletching job is a lot different. The A/C/C's were fletched at a pro-shop and the PSE's are factory fletched .The PSE's have very little adhesive and many are bonded turned up so that the flat portion that should be bonding against the shaft is turned up slightly.Some only half or less of the flat portion is contacting the shaft.There are also gaps where you can see daylight between where the front of the fletch is bonded and the back is bonded ,but not bonded in the middle.
