I think you will find that John C has a fairly good knowledge of lucky productsA lucky stage 2 & 3 with either the Lucky stage 1 or an equivalent aftermarket firing bolt will increase efficiency and decrease cycle time. Coupled with a QEV your Ion becomes very very efficient and consistent over the chrono.
QEV's - We had a bit of a debate previously about the effect of a QEV on paint. It would seem the faster action of the firing bolt caused by the quicker air dump through the QEV caused the Ion to be harder on paint. It was discussed the lucky stages reduce this effect, however, although a lot of conclusions were offered up, not sure we got it 100% confirmed one way or the other.
Not disputing either of you..........
.............But would be good if John C could elaborate on his comment?
