Ok think I am going to try the old way again that I did for 17 yrs with no issues. You guys know my set up so which of these two is the best to go with the 2315 or 2216. The 2216 seems like a log and the 2315 seems to be the spine used by lots of folks with near to my set up. Also have a lot of blazers and was wondering if they will control the heavier arrows in the end. Thanks.
