Well the Whittier curve is extremely tough and there is an 80% chance you won't keep your scholarship there. Nothing against you, but pretty much anyone at an ABA school thinks they will be in the top 10-20%, but you don't need to be a math major to figure out 80-90% of people won't be in the top 10-20%.
Now I don't know what Western State's curve is I tried to look at their handbook http://www.wsulaw.edu/pdf/student-handbook.pdf
, but I didn't see the curve. Generally speaking at an ABA especially one that gives out scholarships based on you maintaining a certain GPA it is very difficult to achieve the GPA. I am just speculating that it will be difficult to maintain a 2.6 at Western, but I would specifically ask them what Western State's curve is.
The schools are about equal, but I might give a slight edge to Whittier, because it has been ABA approved for much longer than Western State, which just received accreditation. I would also e-mail some practicing attorneys from those schools and see what they have to say.
Either way good luck.
