Trying to find some good coils for this rta. The two that came with it worked great. Now the premade coils i bought are too big(3.5mm ID i think) because of the postless design. Definitely a beginner at this and am looking for a good "thin" gauged wire that i can run at a cooler temp. 100W is a little too hot. Prefer right around 65W to 75W or even lower.
