Additionally, I would amend to it "d) rarity for rarity".
A good point Dave but this one can get sticky sometimes too. Here's an example, a guy takes an Añejo 77 and puts a Padron 1964 worth about $10.00. Someone will come along and say "HEY, Añejo 77s are rarer than Padron 1964s, I call shenanigans!" :laugh:
Personally, I'm having a very easy time getting Añejo 77s so I would think that was an okay P/T. Other CPers in other parts of the country probably find it nearly impossible to buy Añejo 77s meanwhile, their local shop is stacked to the ceiling all the time with Padron 1964s.
Now getting back to the other point I raised (about the host calling all the shots) some might say the way to solve this is "Check with the host, it's his decision." Okay I guess BUT the guys who are in the pass AFTER this perceived unfairness about rarity should be consulted as well.
My point is the "rarity for rarity" is kind of tough to define, I'm not sure it really means much or adds value so I'd argue against adding that rule.
I'm certain the host wouldn't allow that kind of trade either. NEXT!!
