Ask Gilly, Vedder and others...nothing "complicated" just a spring or other assorted jimmiemabob that goes tits up on a regular basis and puts em out of commission for a few weeks. They are smooth as butter when running at 100% and as purty as Pam Anderson butt naked but for the $ I dont get the worship factor.

I just compare them to my $50 shimano knucklebusters that have caught upwards of 200 Kings with NO issues up until one finally gave out last year after 10 years of service.
