Though I don't have any direct experience (yet) with this particular tire, I just finished a search for 17" rubber myself and settled on the V70A mostly because it was available in a 335 and was slightly larger diameter (26.2") which helps fill up my big rear wheel wells.
At $235/tire rear (335/35-17) and $185/tire front (275/40-17) at my local Americas Tire Outlet (no shipping charges, only sales tax)...they were a terrific option.
I have experience with the V700; and this new tire isn't that dissimilar. 10K street miles (limited burnouts) isn't impossible, but they'd be well bald by then. Treadwear rating 50. If you're getting 10K miles out of a set of rears on a cobra (any brand), you have better restraint than I do. As little as I drive my car, the tires would be hard and worthless by then anyway.
A set of tires every spring is my plan...assuming I don't see much track time. With track time, one set per event probably...depending on how they wear.
Take a look...
