F1's are the best, I cannot big them up enough. Yoko A539's are good in the dry, but as for wet performance on Yoko's, I have tried Prelli Dunlop Conti Yoko's Budgets and Yoko are worse than budgets in the wet. I got my F1's fitted for £48 all in. About a £5-10 dearer than the rest but boy are they worth it.
