First of all, I applaud both Don and Tony for including instrumentals in their set lists. Obviously, both of you have the necessary playing skills to do that. I was thinking more of the average NH gig, which, as far as I can ascertain, is mostly vocal with accompaniment. Both of you play a lot of CC's and Bar/Restaurant type gigs, and all-vocal sets would start to wear thin no matter how good you were.
My reason for posting this was a reaction to the mad excitement and rush to upgrade every time a new model arrives on the scene. And yes, my post was exclusively directed at 'Pro's' as they are usually the ones that need to justify such a move financially. I personally own four (4) arrangers and other than to piss off my wife, can't justify any of them. But then again, I'm not a OMB; don't have the skill set, so couldn't even if I wanted to. Anyhoo......
