Breeding Suggestions?

Looking to breed these cows to calf fall 2010.  Any suggestions would be appreciated.  Would like to use only clean bulls.  Want to make steers or heifers.  I have Johnny Walker Red, Who Made Who, Hairy Bear, and some others in the tank.  Both Maine Cross cows are large frame soft made cows.  Also have some others like them, but smaller framed. Suggestions?

1st cow: Maine/Charolais Cross
2nd cow: PB Limmy - Due to Star Power 10/3/09
3rd cow: Maine/Charolais Cross
