when i first got my brooks it was slippy as hell and really hard to get comfortable on.
i then was told by a guy i work with to soak it overnight in warm water, which i did.
this removed alot of the shine off the saddle and also alot of the dye, so that your ass wont turn black/brown in the rain.
the soaking really softened up the saddle and reduced the slippiness greatly.
a few coats of linseed oil to waterproof it and i was out on it again happy as a fly on a poo.

worked a charm, highly reccommend it
