I learned these scales from Jens Kruger, and they completely transformed the way I move around the neck and the way I play single string.
To play these cleanly, good left hand technique is essential. Look at my left hand, and see if you can make yours look similar.
Whenever learning scales, its important to apply them to what you're working on. I recommend learning these scales in G, and then applying a fiddle tune melody to them.
That way you don't just muscle memory learn the scale - you challenge your ears and fingers to work together :).
