Depends which version they are. The only shafts that are in the same league as MW are...... MW.
The Unitrax VSP were [barely] fairly close, but the more common and still available VHP's don't hold a candle to MW. In short, All unitrax shafts are still held to the constraints of the U-Joints, inner and outer flanges, etc. The MW shafts replace EVERYTHING with 300M- shafts, flanges, and have large CV's instead of U-Joints. They are considerably stronger in every aspect... but also 2-3x the price.
