Here's a link to her pedigree on Pedigree Query: http://www.pedigreequery.com/queen+dancer4
Her dosage profile is 22, her DI is 4.50 and her CD is 1.00. That means that she has 4 1/2 times more speed in her pedigree than she does distance - that's why she is probably doing well at barrels for you
The DP of 22 is *average* especially when you compare it to the DP of 56 of Fusaichi Pegasus.
The fact she is unraced is a HUGE strike against her as well.
Stud fees can be all over the map, but in order to match her up perfectly with a stallion that will ehance and compliment her, you need to do a "nick" with her and see what bloodlines she will nick best with
When I bred my race mare for a "commerclal" foal the biggest stud fee I could afford was $5000.00 and I bred her to Alumni Hall. And believe me - a $5000.00 stud fee is WAY cheap in the race world! I was literally at the bottom of the barrel but that's all that I could afford to spend. We figured that this foal would get between $20,000 and $40,00 at this year's Yearling Sales in September 2011, but last fall, I sat down with pen and paper and mapped out what I had spent on this foal so far, the fact I kept them at home so my costs were minimal, agent fees, prep fees, auction house fees, commissions, etc, etc and at the end of the day, to get him to September 2011, I was going to have $20,000 - $25,000 into him and HOPE that I could come out alive with my hide intact in the end. Everyone else would get their money and make money off me and my colt - I was the one who appeared to be coming out on the losing end of the stick, even if he did sell for $25,000 or so. So - I cut my losses then and there and sold him
So - go in with your eyes WIDE OPEN. Racing is a very expensive and very unforgiving game ... and there are more people spit out by the roadside with no money left, than you can count ...
Hope this helps!
