Got to disagree on this one... Anything that needs a very quick, facile action to imitate well (accordion, flutes, rapid strings, some Minimoog lines, in fact, anything that actually IS triggered from a lightweight keyboard in real life!) is hampered by a wooden 88, at least as much as playing piano on anything other than wooden 88 is hampered.

I personally feel very little compromise on my technique playing piano on the G70 action (the shape and feel go a long way towards making you feel at home), but most things other than piano definitely take a hit from the stiffness of a real 88. Mind you, a LOT of the budget 88's are ANYTHING but realistic in their pianistic touch. They might make excellent compromises, too, but most of them won't make a true pianist feel at home any more than a semi-76...
