44 lbs. for the 76, 50+ lbs. for the 88, and a tiny LCD screen compared to the huge one on the MoXS (mind you, refresh rate is so slow on that one, scrolling through patches will drive you insane!).

The thing I'd be most interested in finding out is, have they worked out a hands free way to trigger the different arps, and have they found a way to drop the fills in and out any other way than a bar ahead of time? Fix those problems, and you've got a serious contender against an arranger if you want a more contemporary sound...
