Hey, Mike, thanks for the link. Exercise 3 is one I've been working on recently... I actually have to focus to play the groupings of four. Exercise 4 is quite interesting, and difficult to play at a pretty high tempo :)

Exercises 1 and 2 are what I've been playing for over a year now, and they're what's boring... I'm beginning to despise going straight up/down the scale in singles and groups of threes... at least since I hate them so much I won't use them in soloing (yes... I admit it... I've actually played some patterns in my solos before!!! *cries* but hey, I've grown up since then)
