Hi Scott, or Jay??
Before I ordered my pistons I spoke with Adrian over the phone who invited me over to their HQ, where he measured my bores and advised me on options on how to proceed, he was extremely helpful and very personable. While I was there he removed the rings from a set of pistons in order to measure them in my bores. So I knew they were ok to remove, though as you say are thinner than old ones and little trickier to remove and replace.
Not sure my neighbours would let me get away with the static method, so planning on a few circuits of the block to check everything is ok, then a couple of short local runs of about 40 miles each before taking it any further.
