i think the easiest choice on both sides would be a special batch of aviars made specifically for him. between the different configurations and plastics you could have a handful of aviars for various players, somewhat similar to how gateway has a variety of blends of plastic. without seeing any kind of sales numbers i would guess that putters sell fairly well across the board, and if you find one you like you typically stock up and buy more.
most of their good driver molds already have signatures on them (leopard, eagle, teebird, firebird, destroyer, boss), so unless somebody wants to take a gamble on a new disc hoping it will sell their options might be a bit limited. does anybody know if the schusterick stamped cfr pds are a one time thing, or will production pds have his name on them too?
right now the pd would be the best disc to go after in my opinion, as long as it's not off limits due to will.
