there are others who will chime in, that do very low ohm builds, I'll page a couple of em for ya to make sure. But yes he recently began using a button that handles higher heat, cuz at least one guy melted a delrin button or two. Since you'll be getting one from Reosmods.com you'll have the new 510 pin and the new gold plated contacts, you'll need those for the low ohms like you suggest. You'll need a lot of deoxit gold probably if you don't already have that.But I need some help. Please tell me.. Why should get a reo mod? Can it handle my builds? Are there any others things to take in consideration? Should I order replacement parts with the initial order too? (I live in Europe, shipping costs were around 20bucks alone)
As to why a Reo.......it's the best! You can't kill em really. I'd definitely order a couple extra springs, you may never need one, but at least you'll have it. And definitely 2 or 3 extra positive contacts. Rob has videos as do others on changing those out yourself. There is really just nothing to break on these. He'll also be coming out with a metal mod that has a side fire button hopefully before Christmas call the P67. Dunno the price on them yet. You may also want some extra Orings or bottles, but you may have places there to get O rings.
@supertrunker come give us your nickel or dime on this please. Who else goes super low, brain aint workin now, but I know there are several.
If you need Rob (the maker of them) he's a pm, phone call, or email away and will do whatever he can to help you troubleshoot and fix. So will the amazing community here!
