So, I'm thinking of breeding Anfield Road and YNWA on Sunday when the both turn 20, but then breeding a retirement breeding with twins for next years mascot contest. 

Is 3 foals too much? 

are you talking about breeding now and keeping that line going and hoping for good ages or

breeding again next year and having a second line going of what you already have?

I mean, do you do many outside breedings? Because if the lines are all yours, then it really doesn't matter. :P Outside lines tend to not be very popular.

I'd say 3 is okay, more than that starts getting iffy.
