AK jr. -- I think the front and back were identical on the original models (way back), but not for the past several decades, at least not on the LB 5 A model I've been using since late 70s (that means LIGHT BLADE 35"). I have a true RH club; the back side has more loft, though not much. It can, however, be used for delicate LH shots -- I saved par yesterday doing that from up against the wrong side of a cactus in Tucson (I know, hit it on the green, not against the cactus and you won't have the use the back of the putter). After all these years I still love the feel. (I think the shaft design plays a role there). As has been commented on here, when you miss-hit you know it, but a square hit feels just perfect. I replaced the original grip with a standard round one (a bit lighter) and I think it improved the "feel" (for me anyway)
