Size as such may not matter, but I'd choose only the plumpest ones:
like many fruits used as food, these things are harvested before they
reach maturity, and a lot of the seeds will be undeveloped. You'll have
so many that you could try testing a selection for germination right
away: this won't give you usable plants with our winter coming on, but
would be interesting.

I think the consensus is that you'll be lucky if you get a useful crop
of butternut squashes in British conditions: I managed OK many years
ago, during a heatwave ('76, I think it was), but the fruits weren't
supermarket size, and, as far as I remember, I've never tried again.

It's quite easy to get a good crop here (in South Lincolnshire) or at
least it was this year. I grew them in my polytunnel and also outside
and got abpout 30 squashes. The yield was just about as good out of
doors as under cover.
I think perhaps some varieties have been developed for a shorter growing
season. I grew 'Sprinter' aand 'Waltham Butternut' as well as straight
forward Butternut. Unfortunately I didn't keep tabs on which did best.

Obviously if Mervyn is saving seed from supermarket squashes, the
results might be less certain.
