The 3B2S references the Maltby Playability Factor for shafts. It is a code that helps you identify a shaft by flex (3 means R flex), by whether the player is looking for distance, accuracy or both (B means Both), Trajecotory (2 references a medium trajectory) and correction required (Slice, None, or Hook - S would reference a Slice). Whether or not the 60 gram or the 47 gram would be best really depends on your feel preference. Both are considered ultra light for irons, so if distance is your main need, the lighter shaft would be better, as long as it provides a feel you like.
