I have a chance to pick up a ESR 420 cylinder and just wondering the good and bad of this size ESR cylinder. I've tried searching and don't find any info for the 420 or 430.

It's a huge sleeve in the same shell as the other cylinders ESR offers I believe. If your gonna go that big then spend coin on the CP cylinders. My buddy has a 420 on an ATC, Trx 11 port + additional Gauthier racing porting, OOF shearer and it Runs decent but def not like a 420 should.
