The Optimus Solids that I've seen have been really, really smooth; they almost remind me of the IQ Tour in that they tend be early and without a huge move on the back end. If that's what others have seen as well, that could be your answer right there. Balls like that are niche balls, something that is really only appreciated by tournament bowlers. I know that I hated my IQ Tour Solid on house shots, but I loved it when the lanes were tough. Since most bowlers are simply house/league players, there may not have been a need for both the IQ Tour Solid, which everyone already loves as a tournament piece, and the Optimus Solid.
