My only fear, looking at your four-ball list, is that you don't have a pearl in there (unless you have your AO shined to mirror finish). If there's a way for you to go to a five-ball setup, drill the Buzzbomb/R, which should go right in the middle of all that stuff, and you're set.
If you have to stick with four balls, I'd almost consider replacing the THS with the Buzzbomb/R.
