I, like most will be sad to see Troy leave the GP team.
But we have to remember that for the last 7 years he's been riding Ducati's finest race bikes on some of the world's (and Britain's) best tracks and has a very good standard of life to show for it - so it ain't that bad really, I think most of us would like to have been in his position.
Go whup them in WSB Troy, then quit on a high.
