I dont know what size wire you are using but in addition to making the coil a little less in diameter try uping the wraps just for a test. Like up to about 1.2 ohms and see if the flavor doesnt come through more for you. Dont know what juice youre using either but sometimes I have noticed that I get more flavor out of a higher ohmed coil than a say .08 coil. Try it cant hurt. I can say I have had a russian91 and have used both the rm2 and the russian and the rm2 gives much better flavor for me. Also thinking.. Make sure youre not sing too much cotton.. too much in too tight in the coil will choke the coil.. Too little will not work either. Has to be just about right. When you can just pull it through the coil. Not too loose and not too tight. Doesnt have to have long tails.. You can also adjust height of coil once made. try it in different heights above and below the airhole.. Will make a huge difference.
I have tried several different coil wraps from about .8 to 1.8 and found around 1.2 being the best. I use (and only have) 28 gauge kanthal which seems to be really good.
