Thanks for all the info peeps. Iv now decided to go for nakkers twinset cylinders package, I already have the Halcyon type manifold with the big luurvely rubbery soft handles on so il have to use that on my 21% mix twinset fabers! I suppose it will make good trim practise using them buggers eh? I thought i might be able to use manifold on beavers but they dont build kits up n sticker them so iv been told

Re a friend just bought beaver cylinder o2 cleaned with 02 compatible valve but they sent valve and bottle seperate to be built up so hes got to have em built and then o2 cleaned again............?Once again many thanks
