Adrian, not 'smarts,' bud, I just know what I like. Chances are, if I like it and it turns me on, it'll turn somebody else on too. Not rocket science at all, just human nature at work.
Best of luck with your project! I'm looking forward to seeing photos of the finished product. It's gratifying and a ton of fun to bring an old drum back to life and then to beat the hell out of it!
