Thanks Sandy! Just got my 172 which looks like the white board with blue, curving line above. Confirmed, it is a cap. Now I just have to decide if that matters to me. Never was a fan of caps before, but that may just be an irrational bias. They do have the 177 (sandwich construction) of the same year in stock, but I think that's a >26cm waist, which is a bit much for me. Thanks again for sharing your wealth of knowledge.
