I'll never understand all this daisy chaining. I put a Pi3 running as a slave with each controller and eliminated all the long data cables running all over my yard. With advent of being able to run the V3 as a remote, it has become even easier to do. I had 5 remotes last season and had planned on 7, but some props never got built and/or added to the sequences. And it all worked great. With some of the advances coming this year like using a Pi as a hotspot it will become even easier in the future. I never worry about lag or unicast vs multicast anymore. Just my commentary/opinion, YMMV.
