"I prefer the weight because the clamp imposes stress on the spindle whereas the weight does not. I cannot detect any sonic difference in the use of one over the other."

jmeyers- 

So you can fit a rubber washer, place a LP over that and the clamp has enough spindle to dish the LP flat?

The spindle itself is a solid, machine cylinder made of stainless steel usually. How can it possibly hurt the spindle to pull up on it as with a record clamp? On the other hand a record weight undeniably puts added burden on the bearing and thrust pad. Those are wearable items. Somehow, the reasoning of the foregoing statement (see previous post) eludes me. The whole point of a record clamp is that it improves contact between the record and the mat without adding any appreciable stress to the bearing and thrust pad.

I am a user of Spindle Weights only and have in my set up adopted 1Kg Weight as the most preferred. A later addition of a Composite 1Kg weight proved better for tidying the end sound up than the Homogenous 1Kg weight.    

lewm questioned the "spindle stress" statement better than I could.  I was about to ask in a somewhat less scientific way.

Would not a 1Kg Spindle Weight of the alternative Spindle Clamp Weighing 1Kg both place the same bearing pressure into the Thrust Pad ?

Both are Weights that are able to apply additional down force through the Spindle, hence the Ball and Thrust Pad are receiving the point force from the New Load.
