I see. I just dont like polarized setups (played once or twice GPMP taken for 5min. from friend of mine) and at 340gr unstr. it's more stable for volleys and half-volleys; I like it much more than 320gr IGPMP.Like it better now. More polarized, less 10 gr, more headlight and maneuverable, easier to serve... I think also that the RA went down by a margin.
