No, different classes. MBO is Male Bowhunter Open - scopes, 3' stabilizers and stuff. MBR is similar but you must use fixed pins instead of a scope. But you're right about one thing. MBR shoots from the green stake at 45 max. Going through the rules, I see that so do the Seniors classes. (I don't care who ya are, that's funny right there. Youngsters can't hang in with the old farts and mature ladies. [8D]) Crossbows also shoot from the green stake.

I can't keep up with IBO's freakin' rules changes now that I don't compete any more.[&:]
