I felt the same way about those stretches back in the day,then I realized,if I"m going to be playing these phrases at 800 notes per miute,it doesnt matter if I sacrifice a note or 2 just to stay in the confines of a scale,when the point is trying to achieve a smooth,flowing sound.I have small hands,compared to Kotzen,if you see his video,you'll learn about the physical limitations.If there are runs that call for fingerings on the 3rd,5th and 7th fret,I'll "cheat and just do the patterns 4,5 and 7.The important issue is the speed factor.Plus in the process of the self tinkering,I realized if I'm going to hit those other notes,I can just shift my entire hand posistion,and I the process,for appearences,it looks like,to other people,that I'm mving more rapidly because of the shifting.I don't mind.I play the notes my way,thats the important thing.Try it.
