I think that for rooflines, I'm considering the use of smart string nodes. They are a lot cheaper than using the flex strips and I don't feel that the density of the flex strips is necessary. The nodes are spaced maybe 3 times as dense as regular C9(s) with 12" spacing ... and I feel they are easily just as bright if not a lot brighter. Its a different look would be the main concern. But if you mount them into something fairly waterproof, then it works. We did a prototype mounting into a PVC tube and it turned out real nice. I would like to compare the look to regular C9(s) somehow, as I'll have to sell this idea to my neighbor, who (like me) prefers the look of incan. lights. What I would prefer is hanging up ONE set of lights, then being done quicker. The nodes also can be spliced easier you repeat across dead spots as needed. You can use NULL nodes as repeaters and also could eliminate nodes in the software if you wanted. So to me, thats an interesting option, esp. if the waterproofing concerns can be addressed.
