teflon tape and rega RB300 arm

I use the Teflon tape tweak on my Linn Basic arm and the result is very beneficial; a noticeable reduction of resonance. BUT, the Linn is a low mass arm and I don't think the rb300 is, so results may vary.

The only drawback for me is the tonearm now is kind of ugly, but makes for a good topic of conversation.

The Teflon tape has no adhesive, so that's a reason to give it a try. The recommendation that I found online is that you wrap the rear 2/3 of the tonearm and not close to the headshell. That way you wont add weight to the cart.
