HBB you hit the nail on the head saying the CLS works well in a smaller area. I shoot outdoors and in ice arenas as well as my small studio in my house. I don't find the CLS dependable in the first two situations, so I invested in a product called "Flash Wave 2" and "Flash Wave Pro". I found them very reliable inside and out, only query is how they preform in the cold weather (Sometimes I get miss fires, not sure why,perhaps cold batteries???). In the end my $480 CDN for 1 transmitter and 2 receivers was well spent, I think. I take them with me every where I go.
