It just seems so overkill for NH and older folks parties. On a forum where every gram of weight is abhorred in our gear, lugging THREE arrangers (plus all the support pedals, stands, cases, wiring etc.) around to do the job that ONE of them could do seems like such a case of diminishing returns.
Any of them CAN be wrestled into whatever shape we want them to be in (with work and perseverance), that simply seems like a whole bunch of work to lug around three, so you don't have to do the work and perseverance part!
But, no skin off my nose. I'll be interested to see how long you keep it up for, though!
