Mr Jason Becker has some good sweeps that cover your standard shapes & patterns... I would think that his sweeps are quite "basic" in terms of pattern/shape but to attain his smoothness & stamina, well... 8O
If you wish to move to something more advanced, even exotic or more un-usual, you should check out players like Scott Henderson, Frank Gambale & even Richie Kotzen (as mentioned above). Frank Gambale is ridiculous though...
