Edge Pro II
I know the new Edge Pro uses the same bar as the old edge ( with the nylon bushes ) but on the pro II model it's a smaller diameter bar where you use an allen bolt to tighten the tension. In time it wears a groove on the bar itself, meaning it can't be tightened effectively. Has anyone else suffered from this? I have to put some tape around it to make a tight fit.
All in all the pro's new design regarding the string locks on the bridge is a great idea, meaning you can restring without cutting the ball end off.
