Right-Hand Exercises

I made a sheet of right-hand exercises to use during warm-ups. If you want to print one, you can use this pdf:

This may be obvious (re Mandonico)

The problem with playing the extremely high section of the Mandonico piece is that I have to play it without looking at my hands. I can play it great, if I look at the mandolin. But then I have lost my place in the music!

So this is the technical challenge: shifting positions while keeping one's eyes fixed on the printed page of music.

Any other discussion of this tricky area?
