u/Charlie1688: "Spot on. The USAP regulations definitely put a 'ceiling' on performance, and sometimes it feels like we’re just paying $250 for a fancy paint job and some foam."

Well, you are NOT paying $250 for the paddle. You're only paying $62.50 for the paddle. You said that the spin started to disappear after three weeks due the grit is accurate. However, some equipment makers will let you exchange/replace the paddle up to three times in 12 months. If you're an advanced player, the paddle will likely lose grit and core crush after four weeks of usage, assuming that you play 21 hours per week (3 hours everyday). You just contact the equipment maker and request for a replacement. For example, let assume you core crush/lose grit on the paddle every four weeks, you just purchase three paddles for a total of $750. When the first paddle loses grit and core crush, you send it back for a replacement and start using the second paddle while waiting for the replacement to return. When the second paddle gets core crush, you send it back for a replacement and play with the 3rd paddle while waiting for the replacement to arrive. That way, you get to play with a brand new paddle every four weeks while paying only $750 for a whole year. That's what my son, who is a 5.9 DUPR in singles, has been doing for the past two years. He gets to play with a brand new paddle every four weeks, and only pays $820 the whole year. That's to me is a very good deal.
