Since the discontinuation of the Prince Orginal Graphite O/S, I have been reluctently looking for a replacement frame. I bought a couple of the EXO graphite 100's and couldn't really feel the ball like the POG. It serves well and has decent control, but my ground strokes lack depth. Needless to say I have gone back to the trusty POG. I have noticed the Donnay Pro, the Avery OS, and the Head Youtek 107 have similar specs, but was looking for some feedback from fellow POGers.
