Hey guys, I'm looking for a high quality Z41 replacement that I can install an Overready Zero Rez Shorty in put it on a Malkoff MD2. I'm obsessed with twisty 18650s and there's not much out there. I really liked the Overready one but they seem to be out of stock on black and all my e-mails to them go unanswered. Any suggestions? Thanks!!
