It's the nichrome. I know some people really like it. I don't like it at all. Bummer, because it's easier to wrap a coil with it than kanthal.
Builds with nichrome have a lower resistance than kanthal. And i have observed with my own setups--that if my resistance is too low, gennys cook my
juice too much. Mind you, i use mechs only. If you run a dual coil, with a lower resistance--the coils do not get as hot. And i like a dual-coil now and then.
I have Nectars that i'm playing around with.( Avocados are still in-transit. ) 5/4 28g kan on a 2.5mm bit gives me 0.7Ω. My u-wick was only ~25mm wide. I find that my
juice tastes 'off' after about half a
tank. So i will prolly roll 35mm of mesh, and add a wrap.
U-wick for Avocado--cut it on the bias, or get diagonal-cut mesh. u-wicks are a bit of a pain-in-the-..... I found that adjusting its elbows gets rid of the hot legs. Good Luck!!
