It's been interesting to note that the massive differences in tire degration, grip and overall consistancy may reflect badly on a potential Pirelli's buyers decisions to purchase a road tire. It would for me.
If I were to re-tire my 911, I would take a Bridgetone vs a mickymouse Pirelli anyday. The Bridgetone years brought some awsome displays of dominance and professionalism that will stick in my mind for years to come. What's Pirellis legacy going to be? The manufacturer that made one tire that was 2 sec/lap slower than the tire, just to increase the amount of passes per race? It really cheapens the sport and the tire manufacturers image in my opinion.
I also still remember the Bridgetone vs Michelin wars and how badly they made Michelin look. Bridgetone, (through competition) came out as the best tire helping Ferrari and Schumi dominate.
It will be interesting to see how Pirelli will spin this new dawn of F1 tire, made not to go fast or last the longest but to artificially spice up the show.
This in my opinion, is not F1's finest year. I hope the gimmickry will stop and get back to some real racing where best car and the best driver wins.
