I think the iffy tyres are not the issue anyone is complaining about so much as the teams not having enough tyres to make a proper fist of Practice.I would love to see some iffy tyres at every race in the future; can the FIA introduce a mandatory slow puncture rule to keep it interesting.
Anyway, we should at least give 2011 the same chance we gave 2010 (one race - read this tale of woe) and at least give the rules a chance.
You've got to experiment. Almost anything can work in theory. Only when you test it can you know for sure! Anyone who watched Virgin last year will understand that...!
