I wouldn't pay that much for a 66% possible het when you are going to need the 100% het male regardless. Raising him up one season and putting him to a several adult females is not going to set you back more than 1 season in the project. Hold back all of the girls he produces and in 2 years pair him to them. You should be able to start cranking out a fair number of visuals from a 100% het male within 3-4 years only.
