Which Progressive Game To Play

[Casino Knight]

A local casino has a progressive bank that has the following games in $.25, .$50, & $1.00 denoms.
JOB 7/5
DB 9/6
DW 25/16/13/4/3/2/2/1
TDB 8/5
Black Jack Bonus Poker Royal 4000, 4 Aces w/BJ 4000, 2,3,4, w/BJ, 2000,4 Aces or 4 Jacks 800, 4 2,3,4 or 4OAK w/BJ 400,
4OAK 250, 8 FH, 5 Flush.

The Royal Jackpots progress the same for all games.
I have seen jackpots as I high as $5k on quarters, $9K on halves, and $12K on dollars.

So my question for the pro's is which game would you hammer when those games get really high?

At what amount do the become positive?
