See above for Tania's take on it.

It isn't a fully stable variety in terms of growth patterns or fruit appearance/size. IME with it over the past 4-5 years it has an indeterminate growth and fruit production pattern but is more the size of a determinate plant. I started with Fedco seeds and have been selecting seed for round and large since then but still get a range of shapes and sizes and shoulders. But it is a very good tasting tomato, especially for a fairly early variety.

However it has no special tolerance/resistance to any of the common diseases IME.

Here is a link that might be useful: previous discussion about it

Read about it, never grew it.

I grew it last year and I liked the taste but production wasn't great for me. I wouldn't let my opinion of production be a deciding factor for you though! Production can vary year to year for me. Most of my plants had diseases last year due to excessive amounts of rain, so that may have had something to do with it.
