Regina -- I love my boleros. The across-the-back thing doesn't bother me, though. I've never noticed my jersey bunching up under the bolero, regardless of whether it's a race or club cut top. What I like a lot is their versatility because you can wear them over sleeveless jerseys, which is something I wouldn't do w/regular arm warmers (although I've noticed that's kind of a triathlon fashion thing, isn't it?).
