Maybe I sound like a stuck record, but I just want to point out (again! ) that you CAN use arrangers for more than simply OMB gigs and strict arranger play, and for those that like to step out occasionally (or often!) and play with others , you know, those slackers that are always the worst musicians and lazy and have poor hygiene and personal habits, etc., a 76 allows you a MUCH greater degree of choice in what you play and how you play it than a 61.

Not that there's anything WRONG with a 61, or an 88, or even a 45, don't get me wrong. But for gigging flexibility, IMO, it's hard to beat the good ol' 76...
