Ah, I knew somebody up there wants me to hear the Dodson. 12/4 would work out nicely for me.
As far as tweaking the EVS UA, it already comes with some dampening material stuck to the RCA barrel. The RCA is of high quality already, and yes the new WBT Nextgens or Bulletplugs would be more purist, but I don't think either would be as sturdy as these RCA barrels, which you need b/c it has to support a lot of weight on both ends.
Walker SST... Well, I keep looking for some for cheap, and now there's the SST Extremem for more $ I dunno...
For EVS UA, I would have to say, don't fix it if it ain't broke.. Folks, this was a hard lesson to learn that took many mistrials to really "get."
