Anyway, I decided to try the SIT semi-flat Silencers and WOW they are much brighter than the phosphor bronze I was using!! Also, the overall volume went up 20-30%. They are really loud, which I like. And as the name says, there is almost no noise from the slide rubbing on the strings. So, am I happy? You bet I am. I’ll be buying lots more of these.
One other thing I did this time was to change the tuning. (I don't play a lot of bluegrass, preferring a wide range from country to folk to blues). Instead of standard GBDGBD I bought a single 10 as well and made the tuning GDGBDG (I use a similar DADF#AD tuning on my lap steel). The 3 wound strings are used primarily for alternating bass notes, which sound good, and the high unwound strings just sing! Having 3 G notes (a high G as well as the low and middle G notes) really changes the sound of the instrument. There are times it approaches the sound of a steel guitar.
I'm not sure I can out banjo a banjo, but I'm getting close.
