Thanks you two - I thought it would probably be on this site or Simon's but didn't know what it was or where I should look. Will check it out now.
Simon I'll also check out your SAS thingy while I'm at it. I like structured practice as it uses time well, and feel I'm getting a lot out of the stuff I'm doing. But, like overtones I'm sure there are techniques I don't know of which could help me overall.
