I have looked closely at the new SM6 wedges and dont quite see the cog changes. The gap wedges certainly appear thicker in the middle of the club head which would indicate a slighty higher cog than the sm5. The lob wedges appear noticeably thicker at the top of the club head which would indicate a more significant upward shift in the cog than the sm5. However, when comparing the sand wedges 54-56*, the heads appear identical thickness and seemingly no shift upward of the cog. The explanation of the wedges seems to indicate the cog was shifted upward in the sm6 sand wedges 54-56*.... What am I missing?
