Polish tomatoes ?

Has anyone on the forum grown the Polish tomatoes Opalka or Linguisa.
Any first hand knowledge of their flavour and cropping would be of interest as i have used the last of my Amish Paste seed and will need to invest in some similar seed  for next year.

Opalka grows very tall and the foliage is strange and fern-like. So don't go thinking that there is something wrong with them 
Flavour and yield ok, but nothing special, I've not grown the other one.

I look forward to a report on the harvest LeeR ,hope they do well.

Ta for the info Mumofstig , not the glowing reports i have seen from some American sites but worth a try.

Good thinking Trillium i will try to save some seed from this years amish toms as they are our favourites.
I will need to make some flower bags to avoid pollination from the other 5 varieties in the greenhouse.
What to use paper, tea bags , bits of fleece with wire ties.
Any ideas gratefully received .

I grew Aurore last year which hails from the Ukraine (from Real Seeds).  It was very prolific and tasted lovely, but succumbed to late blight, although I managed to rescue most of the crop.  I have to grow outside as no greenhouse.  This year I am trying Stupice as well.  Best to grow varieties with a short growing season as we are in the North (Shipley in Yorkshire).  Also trying Gardener's Delight.
