One of the items in that big Welnick/Scully/Ramrod etc GD auction going- I forget what specifically, maybe the Scully briefcase?- includes several packs of Garcia's Vinci's, both 10 and 11. Before Y!Gearheads/gratefuljams got rolling, around 8 years ago, the popular theory on various GD discussions seemed to be that he used 12's.... just recently I saw an "I read somewhere he used 9's" on Gearheads, proving that even a discussion that yields up correct information isn't necessarily read/searched by its own members.
The internet will always have guesses that mutate into claims, or "I read somewhere's" floating around- that's the nature of the internet and people.
dozin has it correct most of the time because he's actively paid attention to the Y!GH discussion from its very beginning (he's the moderator) AND takes the trouble to post most of the distilled findings (or at least likelihoods) onto his site where it can be easily accessed.
