Just being balanced it does depend on your driving style. No one is ever going to say 'yep - its all good in the hood' because you WILL have less traction with mismatches.
In saying that we've got ditchfinders on the back and Bridgestones that are on their arse on the front - we've never even had so much as a twitch from her even through the winter.
But then I tend not to push it through corners.........I'm more of a straight line man (aka bottle-merchant!)
