Has anyone else noticed that CB has more Robusto's auctioned than other sizes? I wrote them in the hopes to get a better variety going for people to stock their Dor' with but no response to date.

Yes, have noticed. Would like more Coronas and Lonsdales, if not of other reasons then for variety as you write yourself. Having said this I quite like the size of a Robusto as well. My hitlist would probably be: 1. Robusto, 2. Lonsdale and 3. Corona.

possibly because robusto is the most popular size hands down. churchills second.

Maybe so....but like a good Lonsdale every so often too.
