Denny,

For what it is worth, IMO your mare is wide open to Artsplace, Matt's Scooter or Western Hanover bloodlines.
You probably can't get in to Art Major or Mach Three, in which case I would be looking at American Ideal or Sportswriter.
If they are outside your price range give some thought to Always A Virgin, a strongly built and very well performed son of Western Ideal.
