It's time for my trusty 8500X50 to go, and I have narrowed it down to V1 or STi Magnum. I'm wondering if any of the Whistlers are even close. Mandatory: TSR filtering, because it's everywhere here in SW Ohio. I get the impression that the TSR is better in the V1 than the Bel. I don't mind a little other falsing, and I think the range on both is more than adequate. Any opinions and real-world experience greatly appreciated.
