sdandrea1 vastly different feel between the STI and Prophet CB, cb has that hot feel and tink sound, and the STI has a thud feel and muted sound, it took a while to get used to going to the STi's. Size are similar but sha p e is a bit different, STi's narrower in the sole, mid sole, and then about the same in the toe. STI has a grind on the leading edge which is a really nice touch. Super easy to hit, lofts are about the same between the two sets.
