San Marzano Nano- any experiance?

[where_with_all]

I am looking to grow a paste tomato next season. I had some bad disease experiance with Opalka so I am looking for a good disease resisitant tomato.

Of course, I am looking for very high yields (for canning sauce) and great taste too. (i want everything)

I have heard san marzano is a pretty hardy. I have heard this variety will ripen all its fruit at once (handy for making suace).

Any one had any first hand experiance?

Thanks
