Mark.... tank looks great. Those colonies have such a nice shape and grow. 
When I started my SPS tank I had in mind to achieve something like your tank or Matt (Canada) tank. Unfortunately I finish with something in the middle. A mixed reef with a few Acros and some others SPS. 
I do no regret what I have and have achieved. I have many lessons learned from my first experience with Acros and others SPS. 
My tank now is "what it is" and will not change. Also my life have changed since I started (60% of the week out of home and a grandpa!!!  

  ). I will not start it again another tank. I enjoy what I have accomplish. BUT !!!!  For my retirement (~ 7 years)  definitively I will target to have a tank like yours. 
The start points will be bare bottom and only Acros . Nothing else, not a minimal piece of something different than an Acro. 
As I will retire in Florida, nearby our granddaughter, we already have the house built there, I will have to take down my actual tank. Sooner or later. 
The rebuilt will be in Florida and applying all what I have learned, from my own experience and from all the guys, like you, here at RC. 
Cheers and......GREAT TANK !!!
