The 2010 World Superbike Championship grid is beginning to take shape, following the confirmation that two-time World Superbike Champion James Toseland and World Supersport graduate Cal Crutchlow would form an all-new - and British - line-up.

The identity of Yamaha's two riders for 2010 have changed considerably in recent weeks, not least because Ben Spies was contracted to compete in World Superbikes next season up until this week.

Yamaha have moved quickly, however, confirming Toseland and Crutchlow for 2010, thus denying current rider Tom Sykes and Yamaha's new British Superbike Champion Leon Camier a seat with the factory team.

A second complete rider change for Yamaha in as many years, do you think it has made the right decision with its choice of riders? Should Sykes have been given another year, or Camier been given the opportunity following his record-breaking turn on the national scene?
