Sweet spots

Hello David,

Practicing for around a couple of weeks the bends I managed to get a pretty decent 6 draw and finally realized what you mean by sweet spot. Since I was a member of the "2 draw trouble club" but now I have more control, I tried to place the tongue as if I was emulating my old "problem" and it gave me kind of a bend, at least something to start with. Do you think this approach is a valid technique to find the sweet spot on the 2 draw? 

Thanks!
