I personally rate Shinkos at around a 1.5-2 for the fact they hold air.
I have ran them twice on my last 2 GSXRs. Both were remove quickly due to traction issues and poor handling. A good friend of mine bought a FZR1000 recently with Stinkos on it. I warned him and before he could swap them out, he hit the ground.
I would not suggest them for someone looking to have fun in the twisties. For straight line fun or commuting, why not.

Good luck!
