Its also possible you have a touch too much cotton in that particular coil. I know when I get that muted taste out of my Lemo, when I pull the cotton,I usually notice a spec of seed, or one of those little clumps that got wedged inside somehow. With the super-max VG joose I have to use, I have to run really wispy wicks it the Lemo's or I get that same issue. You could try that if the flavor doesn't blossom for you.
Thanks WoW, I will try reducing the cotton a bit. Hope that helps cause I WANT to like this new KF4.
