Yeah and quite seriously, if you manage to pull off every excercise there is in SC and A&R with varying dynamic levels and tempos (without and with metronome) like Stone suggests without breaking your hands, your technique can't be far from optimal =P
I mean at the end of A&R there are these excercises with accents and rolls and buzzes, go try to do those with improper technique. =P
Yup, I'm in love with these books. Can't wait to see how my hand look 10 or 20 years from now.
They will do your hands a load of good, but they can be used to work so much else, too.
E.g. pg. 5 is a treasure trove for coordination and independence. Simply apply an ostinato with one or two limbs and spread the exercises between the other two. Play straight and swung. Play that through different subdivisions over the same ostinato...and so on and so on. I always tell my pupils when I give them their first copy of pg. 5 to guard it and protect it because they're going to come back to it time and again.
