Heard both, and i dont think either set you recommended as an upgrade.. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif Work with what you got first. His doors havent even been touched.Check the classifieds for some used Rainbow SLC 265 Kicks, or if you want to buy new, the MB Quart PCE-216 aren't bad either. I think you can pick them up on eBay for your price range.
