The Warwick bridge weighs a ton. That is is supposed to enhance the wood tone is news to me, in my opinion the less bridge you have the more wood you hear. I hate Fender bridges, but you can't deny that they certainly let the wood of a P or J do the talking.
The Warwick bridge is a work of engineering art, I have no issues with it, but a lot of people criticise it for making all basses sound alike because it favors bridge sound over wood tone. That said, I can still hear the wood differences between my LP Standard, my EB-U with the Warwick bridge and my Warwick Fortress Flashback.
