chakster, I love Reed arms. The 2G is a better design than the 3P. Both use the same tonearm wands of varying masses. The 2g is a neutral balance arm while the 3P is not. The 2G's vertical bearings are two points in the plane of the record (and stylus) with the counterbalance also in the same plane, just like the Kuzma 4 Point. Once you have the tonearm in neutral balance it will stay in whatever vertical position you put it in while the 3P will swing up and down around the balance point like a scale. This is called static balance. For a tonearm neutral balance is always better.
Never tried 3G, but got my 3P "12 Cocobolo for a long time and it's stunning
