I can load the Lehigh NFPJ conversion every bit as fast AND i dont have to install them in a FPJ first or every buy anymore of them.

Sure it takes practice but it is quite easy. Comparing it to a Wolverine FPJ system isn't a fair comparison at all, a DISC action is totally different and any system works fine if you prefer it. I prefer 99% blowby free and far less cleanup. 100% ignition with BH209 is a nice bonus too. The Lehigh conversion requires an Extreme type bolt so you can have the best of both within a minute or 2.
