Well, I'm not going to go back and check what numbers they are, but my reasons for not using mechanicals are:
I don't feel I shoot enough KE for them on deer/hogs
I believe in Murphy's law and want as few moving parts as possible
Not a hater, they just aren't for me inMOST situations.
I'm assuming you haven't ever used one on a deer, then? Is this correct?
I shoot trad, expandables aren't reliable for me and won't kill the deer any deader.
Again....I'm assuming you've never used one....and for your set-up....with good reason.
8. My bow/setup doesn't push enough KE to shoot them.
