Can anyone who has had both of these, or seen both of these comment as to which is better? I'm looking to get a set of new H1 bulbs for my Mazda6 but the Silverstars won't be out until the fall (maybe) and I'm trying to decide if it's worth it to wait, or just buy the PIAA's now. My Tour had PIAA superwhites and it was a great improvement over stock. So I'm wondering how different the Extreme White PIAA is from the Superwhite PIAA, and then how the Silverstars compare to them. Also the fact that the PIAA will run me almost $70 shipped is a concern. This is probably double what the Silverstars will be when they come out in the H1. Thanx!
