You very well may have varying opinions on Ikenvape cartomizers but I will toss mine out here.
I have a slight, and I mean slight preference for the Fusion punched cartomizers over the Platinum punched ones but I like both. It is almost like juices to me, I do swing back and forth and would be happy with either one.
After using a couple of Fusion I frequently switch the next cartomizer to a Platinum. Of course the flange affects some people and if I was limited to one or the other because of the flange it wouldn't bother me in the slightest to be stuck with either one of these.
On drip tips, I do have several steel drip tips all of them fit fine in all the Platinum cartos I have tried. In the Fusions there have been a few that all of my steel drip tips fit except for one. Some of the Fusions are a tiny bit too tight for the Kir Fanis Gemini, (did I spell that right). I can fix that easy enough by stretching the mouth of the cart a tiny tiny bit but some might not like to do that. While I don't have every steel drip tip in existence from my usage I am betting that 95% of the people are not effected by this, a couple of people will find they are a little tight but just fine, then a very small group that will need to stretch the mouth a tiny bit. The Platinum ones again I have never had a drip tip fit problem, a handful of Fusions were a tiny bit too tight on one and only on one drip tip for me.
When looking at posts in the Ikenvape section I see there are some that are in the Fusion Camp and some in the Platinum Camp. I like them both with my little toe slightly in the Fusion camp. Each time I have ordered I have ordered both Fusion and Platinum if both are available.
The slotted ones, I have not tried them yet. When the carto's were last available I didn't get any slotted ones since I knew I like the punched ones. I have not read too much on peoples impression of the slotted ones but since he is making both I am guessing some wanted him to stay with punched while others wanted him to move to slotted. In the order I placed yesterday I got one slotted just to see and the rest punched.
I find I like the standard resistance cartos on my Provari better but strangely I have my Provaries currently loaded with LR. I do like the LR for my lower powered more portable devices and I do use cigalikes for hands free activities and only go LR non-punched Platinums for those.
On Ikenvapes site you will notice he has these Green Auto Ego's. They are surprisingly good with a 3.96v. I like them enough that I ordered some more even though Zombie green is not my color. I use them when the Provari is a bit too heavy or when I want hands free but don't need to drop all the way down to cigalike size. I think anyone who picks up the Auto 350mah batteries will be pleasantly surprised at how useful they are at times.
I do have some Boge and Smoke cartos here but they have been doing nothing but setting in their wrappers aging. I will use them if I cannot get any Ikens but I do like the Ikens better and I want to support the little guy as well.
