Jack43,
Glad you're enjoying the new setup! I've never heard a WT, but from its design I'd expect to hear just what you described on switching to a TriPlanar. Silicone damping seems to work okay in the bearing well of some unipivots but other applications are dubious, as attested by all the negative results posted on this thread. To design an entire arm around it does seem like looking for trouble.
We used to get more "honking" than we do now (which is almost never). Turns out it had nothing to do with the cartridge or arm. It was our phono and/or line stage. I don't know the rest of your system, but that might be something to look at when upgrade-itis strikes again.
If you haven't done so already, check out this thread for some additional tips on getting the most from your new arm:
