if you like the diamaris, the latitude sport would be the successor to this. should be an overal better tire, but I don't think it's in your size. the cross contact UHP is a good alternative if you want to keep the performance aspects. however, all of these are UHP summer tires; you will probably get increased wear over an All Season. A good step with a Latitude Tour HP or even the Pirelli Scorpion Zero Asimmetrico. Both are asymmetric, not directional, so you probably will get less noise out of them then a directional pattern such as a grabber UHP.
