Miserable gits.
Betfair have basically ripped off my theories of several weeks ago

. Then they've gone a spoiled it by calling Button the finest wet weather driver in F1. IMO he's not top 6. Fine wet weather drivers do not crash or fall off the track when overtaking.
A word of warning is that rain has been predicted for the last two GP's and failed to materialise with anything beyond an odd spot. It wouldn't half be good though if it rained in Qualifying.
The best bet of that lot IMO is Vettel because it has a decent chance in the wet or the dry, but especially the wet.
I'll have a hunt around later.
