It seems like it's really a matter of taste between heavy bridges and lightweight, resonant ones. If you're not digging the cast saddles, do some research on bridges that will be a direct fit to your guitar, but a different style. I'm starting to like big heavy bridges like the ones on G&L's, just because I like the notes real bold and sustaining. I just read a post by Lew about the difference between aluminum tailpieces and the Tonepros on Les Pauls. It's either a breathier resonant sound, or on the Tonepros, a much tighter bolder sustaining sound. I like either, depending on the guitar. To me, cleaner tones are better with a lightweight bridge, but heavy gain tones are better with a solid heavy bridge.
