That should be a good area to look for a coach.

Depending on your level of development, I would recomend buying every Robin Hood video made that comes close to your subject. Depending on the level of coaching you wanted, this could be much cheapper, and might help you get more good habits out of your own efforts, before moving on to a coach. I have to say I almost learned more from the Olympic guys than I did from the 3D, not because they were any better, but because they have a different view on things. There are a few new ones I haven't seen, and there are a bunch of older ones that are a little dated. I like Ulmer on form, Wise and Ulmer on releases, but there are at least a dozen good ones.

Next, how about a shooter's school, the PSE one travels the US doing two day shows, they can really pinpoint what your flaw is for you. Or you can go to them in Arizona. You absolutely don't have to shoot PSE, though these folk are so nice, you kind of wish you did.

Good luck.
