I've been running Rodsattack 3s on my ST4S this year and am very impressed. Done 3600 miles and still have 3mm at the centre of the rear. Admitedly I haven't seen much in the way of wet riding but this last weekend I did get the chance to ride my favorite "technical" B road in showery conditions and I think the grip and confidence levels were up in PR4 terretory. Can't fault the dry grip under any conditions and as a bonus they look properly heroic after a decent ride in Summer conditions. The profile seems pretty much ideal for the ST. With the pipes in the "no pannier" position and just dragging the fattest part of the silencer (offside) and pretty much grinding the centre stand footbar away (nearside) there's still about 1mm unused on the front tyre. And best of all the steering has remained sweet, so far. Every other tyre I've tried has deteriorated so much in this regard by 3k miles that I've had to change them. No idea if these'll last until the rear is worn out but I have hope!
Using Conti Road Attack 3 on my GS. Love them. Long life, superb grip wet or dry. They keep a good profile too as they wear.
