Thanks tbk. For those wondering, the book is
PlaneTalk, designed for more advanced players who want to use the whole fretboard.
I'd never heard of 'flextend' before. I'm glad it works for you ... what could be worse for a twanger than tendonitis! I started getting what appeared to be arthritis a few years ago. It was the year we planted tomatoes -- lots of tomatoes -- and we ate them every meal in all guises. I then read that tomatoes are from the poisonous Belladonna family and if you eat to many, you get stiff joints. So I abstained for a while and my joints were fine again.
