I've heard a couple of mixed opinion's on UBARs with carbons shooting thunderheads. So, I thought I'd ask you guys. Do you think UBARs are necessary for deer sized game. If you answer yes, have you ever experienced problems w/ blade retention?
The u-bar is simply an aluminum ring that is designed to give full contact to the base of the broadhead. With the thunderheads this is important if you are using small diameter arrows since they use an o-ring and collar system.
It keeps the oring from squishing over the arrow causing the broadhead to come loose and the blades fall out.

Exactly right! If you shoot T'heads, or any other head that uses the arrow's insert as an integral part of the blade retention system, on small diameter arrows (smaller than 21/64") you need the UBAR's. Just saying they're 'important' doesn't go far enough, IMO. You MUST use them, or you're running a high risk of shedding blades the instant the head meets resistance.
Or you could switch to Muzzy and not have to mess with it.
I am facing this problem, I am glad you guys made the decision for me. thru foam the blades have held fine. Occasionally an O ring will rip going into my mckenzie, but no blades have fallen out yet.

I agree 100%!!
Me too!I used to primarily use thunderheads,and when I went to carbons,that was a problem.The o-ring would get squished.I went to mechanicals,and now I'm back with fixed blades,but I am shooting RM titanium 100's.They have a blade lock collar,that also serves as a u-bar type of adapter.They are a sharp as the thunderhaeds,and seem to fly better at faster speed..I believe due to a smaller cutting diameter(Thunderhead 1 3/16" vs RM ti' 1 1/8")They fit my Maxima's perfectly.They hit very close to field tips too on my set up.Within 1" or so. http://www.rockymtbroadheads.com/97titanium100.html
