Hi Mick,
I can understand the damping that you say resulted, but a WTL of any kind, and I've had them all, doesn't like a dead or massive platform. Only going by all that I've heard , seen elsewhere, or experimented with, I would say while you might be getting some enhancement of something, that the table is having the life, the good feel, sucked out of it.
I so wish we all could snap our fingers like Endora and be listening at each others homes- then some progress on these forums could really happen.
Well, until then, carry on....
