Can anyone give some insight into the appreciable differences between 452, X, Fury, and Mercury? I’ve used 452 and X and honestly couldn’t tell a difference. I’ve never used Fury and Mercury and haven’t really found a lot of information on them compared to 452 or X. I’m shooting a VXR 31.5 at 75#, if that matters much. Consistency is my #1 priority, followed by durability. I’m hell on my bow... thanks.
