If I were you, I'd get something het clown to go with what you have. You didn't say if your 100% het clown was male or female - I think male the way it was written. Maybe pastel het clown female? Pastel clowns are awesome and you could use the pastel in other projects and have het clowns out of that.
I f you want to start breeding next season, you might want to start looking for some good sized females - maybe a couple normal breeders or pastel females 09 and earlier and a 100% het clown female. Your 2010 girls are going to take a couple years to get up to size and your 09 may be ready to go depending on her size and feeding habits, etc.
Just some food for thought. Good luck!
