AHA! So this is what has got you cranked about vinyl. We'll you and I are a bit late to the vinyl party, but I'll beat John TCG to it and recommend putting plasi-clay in every resonant nook and cranny that you can find. I'll also recommend that you look for really good quality vinyl, although many here have decent luck with various thrift stores, flea markets, etc., you may have some vinyl stores around the Austin area. Clean makes all the difference.
