Let us know how the Rosso 3's go. I'm looking for a set as well.
I don't want longevity, I want grip.

The Rosso 3s were very good in the dry but not so in the wet
I recently fitted a set of Metzler Roadtec 01 and they are simply superb !!!!!
Dry grip is every bit as good as the rosso 3 ( if not better) wet performance is very impressive
and as a bonus i reckon they will be good for at least 4k if not 5 whereas the roses were shagged at 2.5k
I fitted the metzlers just before a 2700 mile run round the Picos and Pyrenees and ragged the living daylights out of them and they never gave a single complaint from edge to edge
a few lads on S1000RR are using them as well so don't worry about BHP and these tyres
steering is slightly slower but not so much as to detract from how bloody good they are
