Benz Ebony/ruby in VPI JMW12.5 arm, fluid damping

does anyone have experience using a Ruby or the new Ebony in the VPI JMW 12.5 arm? if so, do you reccommend using the damping fluid or leaving the well dry?
only one way for your ears to know.....add the fluid and hear what they think. had the same thoughts when installing my PT-6. do i or dont i. decided that to swab the fluid back out was an easy task, and immediately liked the fluid installed. kurt
I have a Ruby 2 in a JMW 12. I use the damping fluid - about 1/3 to 1/2 full. I find that this fleshes out the soundstage. Note however, that you need to keep the damping fluid warm in the winter months - a lightbulb clipped to your stand under the arm will do the trick.
