I have two tournament sets with oversized large denomination chips, once custom clay and one custom ceramic. I like the impact of the large chips for large bets. Not sure, but I might like it even better than the all-oversized tournament sets that are the current rage.
I used to own a Crystal Park cash set where the $100 and $500 chips were 43mm and it was also nice.
Those sets mixed 39mm standard chips with 43mm chips for large denominations. Not sure what I would think of mixing 39mm with 40mm. That would probably bother my OCD.
