I know a few people that are running the Invo's on both stock and custom wheel setups. They are a great tire, grip extremely well and aren't too expensive. They also look great imo (I'm running Inov's myself). I personally wouldn't go with the Potenza. I ran them before I got the Invo's and will never go back mainly due to the horrible grip and noise they produced on the freeway here in Texas.
I don't know anything about the Hankook or Continental tires but maybe the Discount Tire guy's (that's who I ordered my tires from) can help you out on comparisons and such
