Rick,
I've recently come full circle on the use of a weight.
I've used clamps in the past and was mostly happy with the results. The nice thing about a clamp is that you can control how much pressure is exerted on the vinyl and thus the amount of dampening you end up hearing. I would not recommend using either a weight or clamp with a soft mat.
When I purchased my Galibier I was very skeptical of the Anvil weight that Thom supplies. I tried it a few times but never really thought much about the sound. Since then I have corrected other deficiencies in my system and now am getting much more resolution than when I first setup the Gavia. In the last week or so I've tried many listening experiments with using the Anvil and I'm now much more impressed with what I'm hearing. The bass has more impact and even the resolution in the higher frequencies are much improved. There is a trade-off in the way of a slightly damped mid-range. Overall I'm very happy using the Anvil.
So, you're just going to have to experiment for yourself and find out what sounds best for you. You should probably find out from TW how much weight the bearing can safely support, but otherwise there can't be any harm in trying different things.
