Been doing some research on trellis systems for grapes.

Are there any references that anyone would recommend for
suitablility/fit and application of the different systems? And some
'how to' instruction?

I'm interested in one called a pendlebogen, evidently a German
technique, but can't find more than a dozen hits on it on the net.
The discusions are fairly light on these sites.
