My personal preference is to just pop greens. Aid Self is nice but eh, requires a fair slot investment to be good and is interruptible.
If you want more survivability I'd go for the softcap.

Either go for the softcap, or take the hopping about pool and get some defense and mez protection if you don't already have it.
Also, dammit, Silas, your post made me read your guides, and your guides made me want to alt again. Must say no to Fire/Cold Corr. Although I really need to make a DP/something Corr at some point, my TA/DP defender is unpleasant.
Looking at my Ice/Cold today, I realized that by rearranging slots a little, I could drop Bitter Freeze Ray and Snow Storm and pick up Aid other/self. Set bonuses are not significantly affected.
I currently run with 32.5 ranged defense and around 31% S/L res, but I enjoy playing aggressively and hibernate, while nice, removes me from the action. In exchange for 2 powers I never use, will Aid self make a significant contribution to survivability, or should I just take fighting pool and go for the softcap?
