I've done one 100% wheat malt batch. And, yeah, it's not real big on malt flavor, but it's a good platform to let the yeast and hops shine. IIRC, I put about 20 or 30 IBUs (Tinseth) of Chinook and it made for a nice inoffensive "lawnmower" beer. It was second batch I ever made that I'd serve to friends without reservation.
