Haven't had to adjust a single thing with the new version on my new KGOs. You should be good to go.
Also, liberty flights order just rolled in. Be somewhat weary of the ego derlin tip they're selling. It fits an EMDCC, but it is an absurdly tight fit. Holy crap. It shaved a piece of the o-ring off putting it in the first time. The taste does get less rubbery with it, though. I'm a fan.
I have a metal one that I bought for my ego mega atty and it fits nice and snug but not absurdly tight. I never liked the metal though, it gave me the shivers. I like the whistle tips and have been saving all the old ones to use on the bottle tip versions I bought before they brought back the new whistle tip. Yikes, these emdccs are a hoot...we are sure having different experiences with them. Truthfully I bought them to use at work for break times, didn't want to alarm anyone pulling out juice bottles and doing fills with only ten minutes to catch a hit of nic. But now that I'm home I'm using the smaller cartos more and just tried a Smoktech 1.7 rejuvinator on the KGO with stunning results.
