It's simple, folks have different tastes and ideas of what looks good while working for them. I like having options. What solves a problem and looks good to me, might not get the same results for someone else. One of the best thing about this forum is multiple solutions are normally given, with good points and bad. This helps someone make an informed discussion. I've learned more thru the years from reading what did not work for someone, expecially when they say why.Why buy a whole new mirror for many times just an extension stem, when the mirrors you already have are just fine? I don't get it.
