hi LSB
Am I assuming correctly that it's Street Money (1999, Seattle Slew out of Silent Account by Private Account?
Who (if I might ask) is on your sires-to-consider short list?
LSB...if your a bit of a gambler...and might consider a stallion that was under the radar...and arguably bred to a very ordinary group at the outset of his career at stud...
...but despite that, still came up with an $825k 2-yo in training (that went on to win a G2)...and a filly that was recently sold for $3mil (after winning a G2 then finishing 2nd in the G1-BC Juvenile Fillies)...
...plus the prospects that he'll have another VERY high-priced 2-yo in training in the next couple of months...plus he is just now getting a real opportunity at stud...and you don't might paying a relatively small stud fee

...you might consider Wild Wonder.
And when you consider that Wild Again (sire of Wild Wonder), when bred to a Seattle Slew mare came up with G1-Suburban Handicap winner Offlee Wild...maybe it's something to think about.
There are plenty of interesting stallions out there that on paper should suit your mare...but I sense that Wild Wonder is a still-quite-young stallion on the move...with a very bright future...and he's already proven he can get the right kind...the kind that can command plenty of attention (and serious money) at the sales.
And the icing on the cake is that you'll most likely get a gray...and arguably that's always worth (at the very least) a little something extra.
Thoughts?
