Brendan, I'm living in a very sunny country and I am shooting in all times of day. The only lens that gives me really visible CA is 80-320. All others (31, 43, 50/1.7, 77, 28-105, 17-35 FE, FAJ 18-35, Tamron 28-75, F 80-200/4.7-5.6, Sigma 18/3.5) don't produce any CA that would really affect my judgment while choosing the lens or taking the shot. In fact, I thought they were CA free until I stumbled on 80-320. And even 80-320 is not really that bad.
With all due respect I seriously think you're paying too much attention to this issue. Cheers.
