I know that our Swimmer magazine had the big article about all the different caps, but I'd like some feedback from you all about the racing caps only. I have a feeling that I'm going to need to wear a latex cap underneath (silicone actually SLINGSHOTS off of my head after a 50). I've done some research and it looks like the racing caps are fitting really tight? Will I be able to double cap ok? I won't be competing in anything above a 200. I'm female and I have a pretty good sized head... any advice? I should add that I've been considering the Speedo Aqua-V (large size), the TYR Tracer, and the Nike Dome caps.
