First off nyk, I do love the heifer you posted in the past, and if I was picking replacement heifers she is the type.
Here is a portion of and article I found, it basically confirms what you are saying, show heifers do tend to go one direction as far as type and look.
An Ideal Breeding Heifer:
Structurally Sound and Correct:
All four feet facing forward, legs and joints correct, with adequate set and angularity.
Takes a long, smooth, stride. Back feet placed where front feet let off.
Level and square hipped, and level topped.
Bold-Ribbed:
Big and expressive through center of body.
deep-middled.
tying into a shallow but wide chest floor.
Balanced and Eye Appealing:
Smooth shoulder, tying into feminine and clean front end.
Feminine and appealing to look at.
Adequate Muscle: While a powerful female is often successful, there is a fine line that divides one from a terminal market heifer. If you feel that one is close, it is okay to get several opinions on how one should be shown. A breeding heifer should still show some muscle expression over her top, rump and quarter, but not be overly massive like a steer.
Ideal Conditioned:
As long as judges are picking a type, breeders are going to breed that type, and the people showing are going to pick that type.
As for her front feet, it must be the picture, in other photos they appear to run north and south.
