Definitely subjective...depending on what you are comfortable with obviously.
Personal thoughts...i would use the pain or buzz depending on your preference for stability - and then use the hell out of it. My game increased drastically when I simplified the mid-range/approach section of my bag. I found I was using 4-5 discs depending on several different factors. While the multi disc approach might work for some who have really dialed in their game over the years, I found it much easier and more consistant to use one disc until I could throw it from numerous angles. Dont get me wrong I still use different drivers off the tee, I have found mid-range/approach to be so much more sensitive though...
Just my 2 cents. Good luck.
