The Synergy II is redesigned like an SL(Thin shaft shape).And the blades are different. And they have always come with a wooden plug,maybe composite now. Is the Synergy II as thin as the SL or is it just a synthesis repainted? I would rather get this than an SL, but if its not thin, im gonna get an SL The Synergy II is a thinner shaft shape than the synthesis, If I remember my last trip to my LHS correctly.
