Hi All, I was wondering if any of you could use your software to run the numbers on these arrows and see if these will be great for my set-up. Easton X7 Colbalts 2613's Full length (34") 220 grain tips My set-up is Apex 7 28"DL 55lbs I will be using these arrows for spot shooting...so speed isn't an issue. Can you plug that into your software and tell me what you come up with? If the 220 grain tips aren't the right size...what does the software tell you is? Thanks!
