Hi there Walt....Thanks for sharing your project...Looks very similar in scale to the one we will be working on......great looking installation over there in Burundi.....Nice work....We had been leaning towards the Flexware gear due to our past experience with it.....Sounds like there are some good options using some of the Midnite gear as well....Some more vetting to do..... This job promises to be a great learning experience......We are looking forward to putting together the best possible system....It is not that often that we get the opportunity work on a project of this scale.......definitely plenty of mental exercising we will be working thru..... Cheers, Kirpal
