I've been using the POG OS for a few weeks now with PSG 16g at 57lbs. I really like the sweet spot size and the stability offered by the racquet. I want to try and make the racquet more powerful and gain some extra ball bite off the string bed. Which would you suggest to help me accomplish my objective here: 1) full co-poly in a thinner gauge at a lower tension? 2) poly/multi hybrid in a thinner guage at a lower tension? Thanks in advance for any advice.
