I ran Roadsmart 2s for street use on my ZX14 for years, but rarely got better than 4k out of them. Maybe the RS3s are better? The Angel GTs have been wonderful on my Sprint so far, and at about 4k miles they still look great and show little wear. I went standard spec on mine, SprintGT only weighs about 590 wet, so the A-spec may be even more tolerant. They've got an elliptical profile so there's more of a footprint on the highway, but tip in doesn't feel negatively affected to where I dislike them. I'd compare the tip in feel of a 55 profile Angel GT to a common 50 profile tire, so if you're a 55 or 60 fan just beware these wont feel quite as good...but they still perform excellent imo.
