Maybe you just need to find the right atty that works for you. My first 2 weeks I built on all 3 versions of the Lemo and have just added the Sub Tank to the rotation. The temp control builds have been just as warm and thick as the kanthal builds if not better. Yes, there were a few bumps along the way, but they were sorted out quickly.
My suggestion to anyone is to get an atty designed to run a single coil. Once you get used to the learning curve of the SX Mini and have no problems then move on to a dual coil device if you desire.
I owned an rDNA 40 and also owned a Lemo. I did have the best results out of any atty on the Lemo but I got tired of the Lemo. Too bulky for my taste and lacking in flavor. Maybe the drop would have been better I don't know.
Everyone is talking to me as if I've never done nickel builds and I'm new to this whole thing but I've done 30-50 nickel builds and still can't seem to get it right. My builds always look perfect but the temp sensing is never where it should be (hits too soon at the temp cotton chars, etc).
I've tried single coil builds in various attys now (authentic Origen, Lemo, authentic Tugboat, did a dual coil in a Magma clone I had for a short period of time) and I'm still just not satisfied with the results. Either I'm really picky, I've had bad luck with the devices I've gotten, or I'm doing something wrong. I also find the builds in doing that other people have done vary quite a bit in resistance from the other people's who have done the same builds.
I'm going to try the water test today in my single coil Origen and see if I can figure out what the issue is. I'm kind of thinking the build I have in there is fine but I just don't like single coil builds or something. May try another dual coil build in the Tugboat too.
