Double Bass Next etude book?

[oliebrice]

what would people recommend after Storch-Hrabe 57 studies, Hrabe 86 etudes, the Billie etudes book and the white Simandl etudes? Maybe something a bit less diatonic?

I'm curious about the Frank Proto etudes, but unfortunately only available in the US and postage is ridiculous, more than twice the cost of the book!

Frantisek Hertl wrote a book of 20 etudes I'm looking at right now. Available as a download. If you know his music, you'll appreciate these.
