I can't agree more with you on that! Although most races are only exciting in the first and last ~15 laps, the season overall is great!
I think the tires do both good and bad. I causes drivers do really be aware of the tires, and some can handle them better then others. Alsonso for example has made the same mistake twice, ending up with worn tires in the last ~3 laps..
Or the Hamilon vs Maldonado moment, Maldonado clearly had the better tires, but Hamilton wouldn't let m pass, ending in an accident.
But, it's not al fun and games with the new tires, because 50% of the race is not driven in race pace. Most drivers have already said so; They're holding back, slower cornering, less acceleration. RedBull's engine mapping did that for the drivers, they didn't even had to worry about it.. And when we end up in the last 10 laps of the race, and team see that the tires are still good for another 15, all of the sudden the fastest lap is broken multiple times every lap..
I'd love to see more tire manufacturers in the game. Maybe Bridgestone, Michellin, or some cheap Chinese brand for the starting teams

Oh, by the way; I've set up a poll on our FB page to predict the SPA GP winner. My vote goes out to Webber!
