My Powerbond is (Got mine at New Era). The SLPs should be as well, since they are just reboxed Powerbonds.

Get an ATI if you can swing it...Not only the lightest but best damping also..

Thanks for the results. I think I will get the 10% underdrive from ATI. The extra dampening has to be a good thing. I could see how the other smaller and lighter units could cause balance issues.
