Unless you only want to buy one pair that can be used for both easy snow/glacier travel and technical alpine climbing, I strongly recommend a strap aluminum model.
Black Diamond Neve Strap Crampons with ABS would a great choice.

Make sure you get a strap model, not clip on.
The advantages are:
1) Low weight (nearly 50% lighter than steel models)
2) Versatility. These crampons work with a variety of boots and even trail runners.
Keep in mind that they do get scratched if you use them to climb rock, but this is not a problem for Whitney main trail.
Pair these crampons with GTX trail runners and UL gaiters from MLD and you will have a vey nice kit for your hike.
