I'll check Thunder out - thanks!
4gasem, I just meant I already got the point about UFO, that's all. I still like to see for myself. On paper it seems to be a great system, plus the one style looks pretty close to stock, which I like. If I got a UFO I'd prolly ask them to install it being they are so close. Then I wouldnt have to worry about any of those other issues. The Marks's do sound great and they are a killer price, but in pictures I'm not quite sure about the looks - that's why I really want to see them in person. The Holeshots seem to be the best all-around, factoring looks and sound, but again thats in front of a screen. Anyway thanks for the input.
