Have to agree with JWK regarding outdoor grown Gardener's Delight - I'm salivating just at the thought of this summer's crop!
Three years ago I tried 'Sparta' as an under-cover crop for the first time mainly due to reading a write-up of taste comparisons in a gardening mag. I wasn't disappointed and have grown them as my main tomato crop ever since.
