Odyssey stroke lab putter grip - Replacement

I know someone who bought a Strokelab putter and changed the grip to a Superstroke. Seemed to ruin the balance of the putter for him and he subsequently binned it. I tried it before he sold it and got on OK with it, in fact it was what prompted me to buy one. I'm happy with the original grip though.

Point of note for anyone else buying one, you cannot buy replacement grips from Callaway, they are not made available, only already installed when buying a putter.....
