Bob since our initial purchase the lovely missus and myself built an addition on to our home for a dedicated room for the system and with hindsight being 20/20 and everything else staying the same, I would have kept the 50s over the 60s because I believe they would have made an excellent pair of stand alone stereo speakers for another part of the house where the volume stays low. Having the 60s is almost like having a second pair of 80s and I believe it would be nice to have differing speakers.
That's the only change I'd make, the 80s, 600, surrounds and centers are a system that I'm extremely satisfied with and have no regrets whatsoever with the purchases but I will add another VP150 to replace the VP100 in my 100/150 combination just so that the centers will both be the same.
