Hey i just bought my first RDA a doge v2/v4 clone. I want to start off with pre built coils but im not sure what kind to get (ie. Fused clapton, clapton, alien etc...) im currently using the kangertech topbox with a .5ohm ssocc coil. Im going to put it on my kangertech until i get my istick pico 75w in the mail. Also i was wondering the differences in cotton and what kind i should get. I was looking at cotton bacon and cotton candy but getting something with alot more product for a cheaper price would be more ideal. Thanks
