Michelin Road 5 Tires

Anyone running the Michelin Road 5s? Wouldn't mind a personal review or any comments people have on them.

I was originally looking at the Pilot Road 4s to replace my stock X rubber, but I saw the 5s just came out a few months back and they're supposed to be better.

One issue is sizing.. They only offer:
120/60 or 120/70 on the front and
150/70 on the rear

Any issues with chain run on that big of a rear? Any clue which front would be the best? I know neither are stock sizing, but I'm unaware of what that will do to the stock ride.

Thanks!

Just ordered a 120/70 and 150/70. We'll see how they perform/fit once I get them mounted up and this snow finally clears
