I'm just saying, if you begin by using two fingers for a bend, you will inhibit your playing drastically by getting into a bad habit. Sure it will work great now, but when you try something a little harder, further on down the road, you will have to work SOO much harder to play it than if you began by practicing it with one finger.

Now everyonce in a while, some might need some extra fingers to pull of some kind of INSANELY WIDE vibrato. Thats ok, just don't make a habit of depending on 2 fingers to bend a string.
