Any preference of using an AP vs Borg & Beck 9 1/2" pressure plate for a BJ8?

I have the DW unit. 500 miles on it now. Why is the release bearing wobbling? See attached YouTube video.
I believe the wobbling is causing vibration to the throwout bearing - notice the wear pattern on both bearings are not centered. That vibration may be traveling to the clutch housing fork, possibly while I feel vibration in the clutch pedal?

I'm currently trying to track down a tapping noise I'm hearing in the bell housing; wonder if it's related. The throwout bearing fork has a little play, but not sure if it's enough to make a tapping sound. The bell housing can amplify any sound, so there's that.

Why is it wobbling? It shouldn't, right?

I recently got a newsletter from AH Spares describing a visit by them to Borg&Beck after B&B helped resolve a problem AHS had had with their 10-inch clutches. They didn't describe the problem, but I seem to recall some having problems with clutches years ago. At the least, B&B acknowledged the problem and worked with AHS to resolve it. Sorry, it's an email and I can't figure out how to post it (too long for a screen capture).

It's interesting, to me at least, that Moss sells 9.5" AP pressure plates and B&B for the 10". You could call Moss and, if you got the right salesperson maybe they would know something. I bought a pressure plate and disk for my BJ8 from Moss many years ago on sale, so probably AP, and installed it a few years ago. It has about 6-7K miles on it and I have had no known issues. IIRC, I have AP king pins up front, and they've been good for many miles.

Should it wobble? No. Why is it wobbling? It's not centered. Is it the source of the ticking sound? Quite possibly.

I thought my release bearing fork had too much vertical play and replaced its bushes (my dad, rather sarcastically, said "It's only got about 50,000 miles left on it"). There was no vibration or any other symptom either before or after the new bushes (a bigger job than it should have been).
