as header anybody tried any Continental Conti Motion or the Maxxis Supermaxx Diamond tyres
a local bike shop has offered me either pair for £140 ish fitted tho I have only used Bridgestone 021's and they are more than £100 more for the pair fitted

I use conti motions, I think they are fine no problems at all with them.  As they wear they don't like white lines very much (what tyre does) and they don't last long, 5500 out of a rear and about 8000 out of the front, I get through 2 fronts to 3 rears and you cant complain about the price, £140 fitted is brilliant, you have nothing to loose as some of the so called "better" tyres don't last twice as long but a rear can cost more than that before fitting.
Going to try the diamonds next.
