The Response - I think that the power pistons are very similar to Trinities superlites. I don't think you are going to see that. Additional machine work to lighten the part usually means increased maintenance. Though real benefits can be realized this way.
Modified pistons can provide some substantial power gains, but usually at the cost of longevity.
There are several ways to lighten a piston by removing material from non critical areas and provide increased lubrication. That's no big deal - it's done all the time and has been for years. Your jetting was way off. The reason there's more height to the piston crown is to increase the compression a bit, though by nature that decreases its mechanical advantage - not good. The thinner head gasket accomplishes that even more.
