Steve:

I use Gary Sosebees Submerged Wood Bridges.

I Quote:

"After wood has been submerged for some years, a change takes place in the cells of the wood. Anaerobic bacteria eat the substance within the cells - the hemicellulose and other starches. This leaves a hollow cell chamber thus improving the acoustic qualities of the wood.When regular wood dries the cells close and become deformed, this the great violin maker Stradivarius, among others, under stood well, and consequently we now know that he soaked his wood for years before making an instrument."

It sounds like a bunch of bull but the bridges are good!

I'll look for that tab when I get back home and get it to you.
