Gosh, I don't really know. I definitely think that wrapping the yarn through your fingers in a standard way can really help even tension....but it sounds like you're already doing that!
I do find that if my hands are sweaty or moist, that the yarn doesn't glide through as easily, and this can create the "sticking" problem you're talking about. If the yarn isn't flowing easily through your fingers, that could definitely aggravate tension problems. You might want to practice holding your index finger out to pick up the slack of the yarn, if it's loose, and hold it closer to give more yarn if it's tight (well, if it's really tight, you'll need to free up more yarn, obviously. If the yarn is sticking, I'll free up a bit more than normal, than pick up that slack by holding the index finger out).
Oh, and if the yarn is getting tangled around the pinky because it's doubling up on itself, just give it a yank from below.
It does get easier with practice. I do think that's the essence of it, as SoapDoc says. Hope that helps!

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
