Thom - I've tried growing both. The harvest wasn't worth the effort. Again, that's probably me being a distinctly amateur gardener. And I can't remember what the heck they tasted like.

Steve - Nope, sorry, going to entirely disagree with you about Lady B's. Good, productive, disease resistant, tasty. Multi-purpose is only an added bonus. I'll bear in mind your Nocila… Noci… Nicola! recommendation for another year, but quite honestly I've given up on first- & second- earlies. I never seem to do well with them. Again, that's likely me failing as a gardener. But I have tried a dozen or more varieties of spud. Heritage & unusual (Orkney Black, and some purple variety), Kestrel's and Casablancas & Christ knows what else. But the Lady B's never fail me. I've had as much as 8 1/2 lb out of one plant (I've no idea what rates as "good" for a main crop spud), and a single spud of 1lb 10oz! It's a good spud.
