Gold tips dont have a very good spining rule. What i mean is that if your shootin a 30.5 at 72 pounds, your right on the line of where your shaft should be spined. All 5575 arrows by gold tip are made for 55 pound to 75 pound bows. If your in the middle area of those two wieghts, they shoot great. But if your on the line then its tough for them to tune. The helical fletching also plays a role. The main thing is shoot what shoots best. Three of us at the store i work at shoot legacys, all at 70 pounds 30 inches. The other 2 guys shoot gold tips just fine, and im even thinkin of goin to them, but they both are on the line of spine. Just my 2 pennys.
