Opalka, NAR, Mort. Lifter, Brandywine are all huge plants in my experience - easily 8'. Sweet 100 is even bigger - more like 10-12'..

Black Krim, Tula, and Cherokee are smaller plants IME and should do fine on a 6' fence.

Never grown Black Plum or Italian Paste (several diferent varieties with that name) or Blondkopfchen.

You might want to check out all the info on all of them on Tatiana's Tomatobase.

I checked two sites which usually give heights:

V = the big French database Ventmarin.
http://ventmarin.free.fr/passion_tomates/passion_tomate.htm
CF = the Cultivar Finder at the forum we can't link to or name.

Black Plum:
V = 5'10" - 6'6"
CF = in their 4'-6' category

Italian Paste:
V = no size listed
CF = variety not listed

Blondkopfchen:
V = 4'10" - 5'2"
CF = in both their 4'-6' and 6'-8' categories, which I interpret as perhaps 5'-7'

Thanks for the resources, I hadn't seen those yet.

So it looks like Blondkopfchen, Black Plum, Black Krim, Tula & Cherokee are good ones to try along the fence. I'll try an Italian Paste there too (the seeds were a freebie from TomatoFest, just listed as "Italian Paste", figured I'd try them out).
