I've been told by several well-endowed men over the years that they prefer bigger girls, as the smaller ones they had been with couldn't accommodate them. There are other men who are well endowed who prefer tiny girls.
I recently lost a LOT of weight, so can speak as a very very large girl and now as a just above average girl - I notice no difference in the amount I can handle. Therefore, I doubt body size has much to do with puss size. I can't speak as a spinner, I won't have those proportions after I'm dead five years.
I've had great sex with guys who were tiny and who were hung like a donkey. There is a niche for everyone.
