I've used 2 methods to level the b and/or e. Buffalo horn bridge pins on the G,b,e usually(not always) mellow out the sizzle if that's the sound you're looking for. I've also pulled the saddle, and sanded a little bit on the bottom directly under the b string, the length of the compensated area. This results in less transfer of energy to the top. Don't over-do this or the b will quieten too much.
