I think the majority of us would never tell you that you are wasting your time. Some may suggest that they believe it to be overkill and that they would do it differently but in the end it is your decision. Most of us can accept that other people have different opinions and different ways of doing things but that doesn't necessarily make them wrong or dumb.

p.s. I am yet to be convinced that the dual receivers of Weatronic or the RRS system have much practical benefit in terms of redundancy. There must still be a single circuit that selects which receiver to use and if this fails you are still up s**t creek.
