I used to shoot the original Scott Calipers but changed to the Lil Goose when I went to the string loop. You use a loop and you won't have any problems. The Lil Goose has a smaller jaw which helps in loading on the small loops with my carbons. All Scotts are great. Just buy the one that fits your purposes. When you get it check for any burrs and polish them out. It'll help save the servings or loop.
