You make the call

I am hosting my first cash game in about 7 years tomorrow. $.25/.50 no limit hold em.  I host a monthly tournament.  The Bicycle's have been used 1 time, the Kem's are new, the Dal Negro's have been used around 30 times, and the Modiano's have been used approximately 20 times.

Kems

They're kems, and they're new. Enough said.

Ditto!!

I'd definitely go with bridge size cards, so that rules out the Bicycle Prestige cards.

I'm partial to KEM, but I've never used Modiano or Dal Negro.
If you've got an oval table I'd go with jumbo, and on a round table with standard pips.

Kem

Post-USPC KEMs suck, so they are out.  If these are pre-USPC KEMS then these win.
Modianos are my favourite, but you specified Poker club, which are the bargain variety Mods.
Bicycle Prestige are nice, but Mods are better.
You did not specify which type of Dal Negro.  I will assume Torcellos and thus vote this way.
