Great info ericsson, thanks. I always thought the 1st gen Pure Control is heavier than the 2nd gen, but they are actually the same, 330g unstrung? (I have owned many of the swirly's but no 1st gens, always thought they are 335-340g unstrung) So does the 1st gen actually have a similar swing weight to the swirly 2nd gen? The 2nd gen's swing weight is perfect for me. I'm guessing it'd be less maneuverable though with the 320mm balance.
