[OLED Screen Source]

i have heard but not personally verified that large screen dna40's will work to swap screens? 

i am also curious if the screen from the rx200 can be switched into a reuleaux dna200?  the rx200 is cheaper than a new dna200 chip and screen...

[people say I don't like tc]

hi, ive only been using temp control since black friday when i bought a reuleaux dna200.  i started with 30 gauge dual coils, in a velocity and a mutation x v2.  it was never fully satisfying.  then i discovered i would have to rebuild every time i rewick - that just doesn't work with my lifestyle.  when i went back to my fav kanthal builds i could tell that i liked the temp control, but not the tediousness of rebuilding and rewicking all the time, and i hadn't found a build that worked for me. so im currently experimenting with ni200 claptons, before i order some ss or ti.

basically, the learning curve is a bit of a pita when one has already gone through it with kanthal, and unless i can find a build that can handle a lot of airflow without being airy, im with @Wing, but mostly because rebuilding 30g dual coils every other day sucks.

[ni205 and ni200 claptons]

i have been using ni200 claptons (24g core wrapped with 32g).  its a much better vape (to me), than dual 30g coils, but i have only tried single coil on a velocity rda because 8.5 spaced wraps on a 2.5mm comes out to 0.07 ohms.  its much easier to rewick without deforming the coil, and a dental brush will clean the coil relatively well. 

make sure you upload a proper csv file from steam engine, it made a big difference.  also, using the device monitor in escribe helped me dial in my settings - 88 watts, with 80 watt preheat @ 3.9 for 1s, temp @420.  bottom airflow full open, top airflow all closed on the velocity rda.

i haven't been able to try ss or ti yet.  still trying to perfect ni200 builds.
