Double post!
looks good you just need a higher pressure pilot.
what were you shooting?

The energy in a light piston will be essentially the same as in a heavier one.
Energy is force times distance - and given the forces will be (more or less*) the same, and the distance will be the same...
*Okay, the faster piston means you have to account for Bernoulli, but the effects of that are small at the speeds we're talking about.
Essentially, a piston in a given valve (at a given pressure) always attains the same energy when opening. The trick is to get as much velocity as you can for that energy, which is done by lowering the mass.
