Hey fellow Tradagangers, If you were considering trying the two tracks string scallops, I HIGHLY recommend them ! I shoot a Great Northern Bushbow three under and have used homemade wool puffs for years. I noticed three things by switching to the scallops. (1) usually shooting 3 fingers under is louder but after switching to the scallops, my bow is a lot quieter ! (2)As a bonus,I picked up some unsolicited speed...approx 4-5 FPS. The scallops were literally 50% lighter than the puffs... and (3)how much easier it is to adjust them in the tuning process.They slide very easy up and down the string. Fantastic product !
