I'm not a huge fan of guitar voodoo- you won't find me filing away the nut in between the string slots, or clamping things to head stocks.  All these things can change the tone of a guitar in theory.  Does they contribute to an audible difference?  Meh.  But the more important question is: does it make the guitar sound better? And that of course is the unanswerable question.  What is better?  So many things about guitars are chocolate and vanilla. I had a Gibson Lg-1 that I loved and it was the quietest, sustain-less, thunkiness guitar I ever owned. Part of the fun of building resonator guitars is that because they are so loud, small changes make a more audible difference.  I've always believed that the more you can do around the bridge/saddle/biscuit on a guitar the better.   That's where most of the vibration is happening so it makes sense that you can affect the most change there.   Something I've started doing is slightly hollowing out the bottom of the biscuits, leaving a border around the outside edge where it rests on top of the cone, and where the cone screw goes into the biscuit.  It's not for weight savings - the amount is so little- but it's for vibration.  Think of the top of the biscuit as a mini sound board.  Just like when you thin the top of a guitar you are able to get more vibration going and that's always a good thing. It's added some openness to these guitars.  It's slight, not as drastic as using a rosewood saddle compared to a maple saddle, but it's there and it's fun to do so I'll keep doing it until convinced otherwise.
