Do you really NEED it? Why?
Bow "accessories". "Need"........or "want"?
I'll give you "need" on a rest. For most of you guys, I'll concede a sight, as well (though, it's completely optional).
What else do you "need"? Why? Has perceived bow noise been an issue for you in the past? Have you tried to mitigate the problem with a heavier arrow? Maybe turn down the #-age?
What's Needed.....and what's "for show"? Nothing wrong with either.
