Not terribly impressed with Roadsmarts to be honest, yes they are great when new, excellent grip but they don't wear too well, this one shown below has done about 3,700 miles, steel cord showing through, and it was bald at 3,000 ish.
OK, they were a fairly hard 3,000 or so miles on the back of my 1100

, one of my mates thought I'd been on a track day

Had to nurse it back from the ferry at Hull on the last leg of my 7 day france trip, I never let my tyres get this bad but I was just shocked at the way it disappeared in front of my eyes while we were away, handling went really bad towards the end as well, because due to the hard centre section it wore like a "Threepenny bit" shape and you could feel it steering from the back when you tipped it into corners.
Michelin Pilot road 2's get my vote

, I've had one on the back of my 954 Fireblade for almost 6,500 miles now ( its almost shot ) but its worn very evenly, not flatted at all and still handles well.
Cheers,
