I'm after a bit of advice

Last service I popped a new rear tourance on – I've been happy with the general wear on the tourances, and the grip from the rear even on the loose stuff. Now the front is up for renewal. The one thing that disappointed me was the front tourance off-road. Even on gravel it never really inspires confidence and anything looser is a bit more exciting than I like my riding to be. Road performance has been fine (though it's got a bit sketchy now)

What's the general consensus on running different brand tyres front and rear? I'm thinking of swapping to either a pirelli scorpion or an avon distanzia for the front rather than another tourance. I can't really consider anything more off-road-biased due to the road mileage I have planned over the next 6 months.

As usual thanks for any and all comments and experiences

Cheers
