On an unregulated mod, I have come to prefer a warm dense vape that I get from using lower gauge wire at around .2 ohm. This is pushing the limits of some batteries, but I have a large quantity of mechs (30+) that are topped with RDAs built like this. I do know what I am doing and am using good batteries. The only thing different about the Paps from any other mech (when considering amperage limits) is that the top cap has springs in it. But something like a Fat Daddy Vapes 510 connector also has springs in it, and this works fine, so the paps should work fine too, as long as the spring is decent quality.
We have designed our springs to be very stiff, choosing a rhomboid shape for better stability in GPin's limited place, made from heat hardened 302 SS. Possibly, they may withstand your test.
