Here is a list of all of the HOY's for the 1990's:

1990 - Criminal Type
1991 - Black Tie Affair
1992 - A.P. Indy
1993 - Kotashaan
1994 - Holy Bull
1995 - Cigar
1996 - Cigar
1997 - Favorite Trick
1998 - Skip Away
1999 - Charismatic

Only A.P. Indy has been fantastic. Holy Bull has been serviceable as a sire, but surely hasn't replicated himself. Cigar is infertile and the rest didn't do anything in the shed as of yet (Criminal Type and Favorite Trick are now deceased).
