We ran the Pirelli 150's last year and are on the 140's this year. I think the big benifit from the 140's is that as in the picture above, you can see with the 150 profile, you cannot get to the edge, which I believe hampers some of the tires ability to let the sidewall work.
With the 140's, I am on the edge of the tire now and have a bit more feel and stability and as Rexbo has shown, these things can get you a track record.
Another advantage I am still exploring is that I have a set with 7 trackdays doing 2 to 3 sessions each hour (I ride with Z2 Trackday providers) and 1 race weekend and although switching them out for a new set at AFM's last round, I am going to throw the old tires back on for every trackday as I want to see how far I can get this set to last.
$$ for $$, the Pirelli setup is king by my wallet thus far.
