cmac, I'm curious why you informed of redshirt to begin with? At D2 / D3 I never inform of redshirt, and I've been successful in getting freshmen to accept the RS 22 out of the last 25 times I tried with no drop in WE. One other time, I had a modest WE drop that I could live with, and only 2 freshmen hated it so much that I had to pull the RS back.
I just think at D3 the saved cash is worth more than the extra 10% of security that they'll definitely accept it.
