S70SX is a fully weighted 76, same as an 88 wood... not surprising it weighs a fair deal.

Still think if Yamaha made a lightweight 76 S910, maybe the NP10 keybed, expanded S910 case, the thing would be maybe 30 lbs. or so. Got a feeling this would be a seller, but Yamaha have no interest in making it. They THINK they have that market covered with the YDG's, but personally I think they are selling us short. They may have the action, but they certainly don't have the arranger we want...
