I have been using absolute for years. It is no more difficult to use, IMHO, than any othe scheme. In my opinion it is all in what you learn and I started with using pixelnet which is universes of 4096 channels. I do make changes in my layout every year. I for one find universe and channel notation confusing as heck, the last thing I want to figure out is dividing a props channel count by 512 or 510 in order to figure out how many universes I need when I can just pick a start address and the total channel count. Also I would never tell you (like some folks are) that there is only one way to do something.
