All the new LP grands come already upgraded with the new gold contacts. Sub ohm ready. I have a rm5, I can't speak for the rm6. I like the rm5, it produces a lot of vapor and you can still get good flavor from the big atty. instead of holes it has two air slots, the air flow control is an adjustable ring you can either close off or open all the way up. The deck is all stainless steel and large so it's easy to build on. the
three posts have horizontal slots rather than holes for multiple applications. Perfect for just about anything from flat ribbon wire to thick gauged kanthal. I've put two strands of 24 gauge
thru the posts and still have room for more in the post if needed. The atty is really meant for dual coil primarily, but I've ran a single coil in it before and it still performs really well. The rm5 doesn't come with a drip tip but that's not a deal breaker. As far as I know, not many people use the rm5 for whatever reason, but the ones that do know it's a different kind of animal.
