Yes the Annual is a good show to go to.
Thank you very much for your answer. I want to ask why you do not have a recognized variety of fuzz under the standard. Even these mice having a very good body type and color.MouseBreeder said:Fuzzy isn't a standardised variety here, so you can't show them unless there's an unstandardised class (these do exist but not at every show and not that often). So the only fuzzy you'd get would not be an exhibition type mouse. If you already have the gene I'd recommend crossing to some big typey selfs like PEW or cream to improve them.
The other varieties you mention have a few breeders. For Siamese try loashu on this forum as she has good mice and has done some recent winning with Siamese. As for the Himalayan you would get better mice by getting Siamese from Kelly (loashu) and a good trio of PEW and breeding them together to make your own.
