Round lettuce?

@Fat Controller I've just been reading your thread from 2013 about round lettuce, it's my favourite, I'm just wondering if you found the variety that was it, or close to it? I've delved into it a little bit and it looks like the "all the year round" that @Freddy mentioned could possibly be the one? Or did you find something else?

 

‘All The Year Round’ was my dads favourite. I probably prefer Cos myself, but if I wanted a loose leaf, I would choose that one.

 

Cos was the one I used to eat until I found the round lettuce, I've ordered all the year round and a Gustavs salad seed so I'll see how I go with those.
