Hey beast!
I haven't been there in a while (years) but I know for sure that a "big" posse of young strong boyz is often chillin' there, throwin' moves in da woods and doing hard first ascents of problems that I put up ten years ago!
Sorry for the stupid rant, people climb in Sasso, should be ok.
Depending on how much spare time you want to invest in climbing, there's mount Amiata at a 40 minutes drive from Sasso, at a much higher altitude. Bring the mat!
Bring the bike as well.
And if you like, please give me a call and I'll give you tour of ze blocs!
