Far freakin' out. I have this mental picture of a tonearm with fishing weights and paper clips hanging off of it, and let me tell you, (in the immortal words of David Letterman), it couldn't look more lovely. :-)

You're right Zaikesman, it's a piece of art. We didn't bother to make the paper clip perfectly straight before re-forming it into the "U", so it's a little squiggly. It ain't no stinkin' Morch or SME, lemme tell ya. :)
I was a bit worried about resonances, but A/Bing with and without it we haven't been able to detect any. Unlike the infamous resonating VTF spring on an RB300, this clip is symmetrical with the bearings, touches only the arm itself and is coupled via the lead weights. Even a large size paper clip is too thin in cross section to pick up airborne resonances, especially given its slightly squiggly shape.
Hi Doug. I agree that this is a nice mod, and makes the small incremental changes of VTF very much easier to do on the OL Silver arm with TWL HiFi mod.
I have installed this on my arm, per Doug's instructions, and have found it a worthwhile addition to my system. I have not noticed any negative aspects of resonance added by the presence of this item.
I think it is an innovative idea that solved an annoying problem of very small incremental VTF changes that are required with temperature change to the very VTF sensitive Shelter cartridges.
The fact that the clip is located at the bearing axis, allows it to be used to give a small but very useful range of adjustment in addition or subraction directions. Plus, it does so in such a way as to not affect the resonance characteristics of the arm, because it is not actually connected to the arm tube, but is indirectly coupled thru the HiFi mod and bearing axle.
This is a good idea that is simple and effective.
Thanks, Tom. The inventor has a Ph.D. in metallurgy. Bet he never imagined he'd be "famous" for twiddling a paper clip.
OTOH, Paul's first patent had something to do with a bucket of water and a tea strainer as a model for improving copper casting practices. Don't ask. Saved his company gazillions and per his employment contract he got paid $1.
Obviously the Twl seal of approval is a far better reward.
