What counterweight to use?

[JasonD]

I recently purchased a bunch of 7.5" LC pads and matching 6" flexible pad holder from TOL, and finally got to use them this past weekend. I was originally told that the factory counterweight would be sufficient but found out very quickly that it wasn't entirely true. The setup was beautiful all the way to setting 5 on my PC, anything over that and it was blister city. What counterweight should I switch to and where can I get it?

Use the 6" counterweight, which you might already have- it'll still vibrate a bit with it, as those are sorta big pads for a PC (IMO).
