Depending on your goals I find using a boosted "A" stallion to high red papered mares creates intact supirior fillies . The colts on the other hand just about always get snipped.

Follow-up question--what about a C stud boosted to a B? Would I be best using his straws on a C mare?

To get more equally intact foals I would do c to c unless your specifically trying to boost the quality of a colt or filly.
Like for instance I pair red foundi mares to A papered studs and only use the fillys I get. Doing this I get alot of supirior fillies. So my 2nd gen mares in pasture are mostly blue papered. Now for colts I select a couple foundation mares and boost them to blue and pair them to an equally papered stud "A" I tend to get both good fillies and colts. I take the colts that are supirior and put them into pasture with the blue mares. Since these mares are slightly less quality compared to sire the resulting fillies end up mostly supirior compared to the 2nd gen mare. Then breed that top stud to a mare that had both boosted parents for supirior colt. But that's what I do. I would think if it were reversed you would get better colts than fillies and most of those fillies would end up spayed.
This is an uneven paper breeding but is even lined. I e found it had worked for me but everyone breeds differently. I would try what you think is best for your goals :) hope this helps.
