really u wouldnt think u would notice much differnce between the value 510 clearo and the T4 a 2.2-2.6 and 2.2-2.5 but the valu ones rated only to 2.5 seem to get warmer producing a warmer vape but they have very cheap threads, I plan on getting 2 1.6ml Clearos and then keep the smaller T4s and G5s around for different flavors I know I like the EVOD it has 1.8, 2.2, or 2.5ohm heads http://www.goodejuice.com/store/kanger-evod-replacement-coils-5pc-p-981.html
the Kanger mini T3s uses 1.5, 2.2, 2.5 ohm heads I would be swapping the 3.4 and the 3.7 battery with them, im thinking I like the EVOD better and 2.2 would probably be best for both batteries?? Any suggestions I know its all kind of taste preference but also its performance looking at the chart, a 2.2 would be good for both wher a 1.8 can be but close on the 3.7 http://25.media.tumblr.com/tumblr_m9dkanCt0I1qc8949o2_1280.png

The ohms are stamped on the coil unit as below. Find out what you have and order the same - they come in 1.5, 1.8, 2.2, or 2.5 (sometimes called 2.4-2.6)....
