Found
this decently helpful video review. I was thinking, though, that the big difference just seems to be that the metal pegs on the lever are just the same size. That's been my only concern about adding a couple of holes to my GLC level belt to allow for similar kind of adjustment- the sets of pegs have slightly different sizes, I'd be concerned it might slip or something. Otherwise I'd just add 2 more holes on the tongue of the belt, just like the SBD, though there might be other reasons why that's a bad idea. Seems like something that would hardly be patentable (not 'non-obvious' enough perhaps?).

this rather useless review.
