Looking at a new Montana and have read/seen about the AMPS mount for it. My question is, how durable is the mount? I plan to use it on a KTM 950 SE and 450 XC with appropriate RAM mounts. It seems like if it locks the montana in the mount with the security bit that should hold it pretty solid but just debating about a TT mount (what I'm coming from). feedback on the mount now that they have been out for a while?
