Gary... I think I have to agree with Donny on this one ... we know he has a LARGE set-up for his BIG gigs, so if he can use a small monitor to add 'just enough' additional sound for small gigs, why not ... less to carry and set up ...sounds right to me ...
Perhaps if Donny liked the BOSE system he wouldn't have to be concerned about this, but that's why they make vanilla and chocolate, and BOSE and Mackies and etc. ...
