Hi piglit,
Jeanette lee, Allison Fisher, Helena Thornfeldt don't play against men. Karen Corr "Irish Invader" is the only one who plays against men regularly as a member in good standing of the Mike Zuglan's Joss Northeast 9-Ball Tour. I refer you to the 2003 combined winnings list. At least 1/3 of Karen's winnings came form playing the men on the Joss Northeast Tour. Keith McCready has played Karen and would be a first class judge of her skills.
Johnny Archer $131,460.00
Francisco Bustamante $118,975.00
Efren Reyes $106,050.00
Alex Pagulayan $94,513.00
Thorsten Hohmann $91,500.00
Jose Parica $75,670.00
Karen Corr $62,165.00
Jeremy Jones $55,485.00
Rodney Morris $53,475.00
Mika Immonen $44,418.00
Earl Strickland $43,547.00
Jeanette Lee $43,150.00
Tony Drago $42,500.00
Charlie Williams $41,669.00
Allison Fisher $41,000.00
Santos Sambajon $40,975.00
Ralf Souquet $34,585.00
John Schmidt $33,252.00
Helena Thornfeldt $32,290.00
Danny Hewitt $31,130.00
Of the men on this list that I know of Karen has defeated Mika three times. Danny Hewitt, Charlie Williams and Santos. She has played Keith and never beaten him yet?

As for this 2003 money list the ladies are ranked about right but three of the big four don't play against the men in a regular tour. If you study the Joss results that are aviable Karen finishes in the money about 9 out of every 10 times. The stats are very incomplete.
Allison doesn't play many men, Helena practices against men, and Jeanette plays in tournaments like the DCC for show not for the prize money. One of Karen's favorite expressions is there is money to be made on the Joss Tour.
Oh, Karen is one of my favorite women players so I am biased.
Cheers,
Gremlin
