Hmmm... not sure if I've ever heard of a "best" truss rod.

This debacle didn't happen at Long & McQuade, did it? If not, there's a great guitar tech at the Keele & Steeles L&M, Darryl. He really knows his stuff and always gives you a little extra on top of what you paid for. Plus, he's always willing to take a couple minutes and talk about tech stuff, even when he's super busy (which is almost always).

If you want, I can give you the L&M phone #, I'm sure they'll take care of you!
