One additional comment here. RE: Longevity vs. grip. I am not an aggressive type rider, so extra grip was never an issue for me. I am a higher mileage rider and therefore prefer a tire with some longevity.
The previous iterations of the :spyder2: rear tires always gave me 10K to 15K worth of tread life on the rear tires. The 2011 has almost 17K miles on it, but will get a new rear tire when it goes back into service in the spring.
The 2014 gave me 8600 miles--which is better than most of you folks have posted--so I am not complaining--to much.
A "normal" riding season for me is about 15K to 20K miles now. This summer I put on about 12.5K over three different :ani29:'s. Each tire change costs me $350 plus. The latest on the 2014 was $421. If I have a normal riding season, that's over a thousand bucks just for rear tires. This could soon become a deal breaker.
I was told the "new" tire I put on was from the new "harder" compound. Time will tell. I have almost 2K miles on the new tire.
