Michell Technoarm vs Origin Live Silver vs ???

Michell techno weight and origin live structural weight...which is better

I've been looking at the counterweight issue for my RB300 lately and there seem to be quite a few options.
1) Michell Technoweight, including cart head weight adjustment
2) OL structural modification, mostly to replace the plastic stun of the RB250 with a metal one and add a different weight
3) Kerry F2 titanium counterweight. Its hole is off centre to lower the gravity point
4) Groovetracer counterweight , about same as above
5) Pebbles counterweight set (incl. stub)
6) Clearaudio Turboweight (I have already ordered this one for my RB300)
7) Expressimo counterweight (similar as above 3,4,6).

The prices range from 50 euros (Pebbles) to 170 Euros.

anyone here have the idea which one is better between michell techno weight and OL Strutural weight

TQ

I used to have an OL Silver, using it on my Teres 255 with Shelter 501Mk2 and now ZYX Airy 3xsb. I switched out the OL Silver for an AirTech MG-1 tonearm, and found the Airtech to be a significant upgrade - really no contest, based on my experience. The price of the Airtech went up, but still, it's possibly the best arm for the price. Because stytlus is tangental to the groove and because there is little or no friction, it seems like a great approach for so little money, especially because it's design is so close to Air Tangent, but at a tiny fraction of the price.

I think that you can't go wrong with either one at their price points. As a matter of fact price may be the determinating factor. If you could find either one in good shape, used at a good price, you have done very well.

Lately, new stock seems to be the only thing availible, which to me says that if used arms become availible, then they either go to someone they know or they sell very quickly. In other words - Highly Desireable!

Remember shopping is free - it's buying that can be expensive.

Enjoy your music!
