I'd like to see Smart Troll data on it before forming an opinion. Sounds too good to be true, but ya never know. Smart Troll is really only guaranteed out to 300' even though it can work further. So, I'd imagine it'd be tough to get great data on it.
My problem is I'm so vested in copper set-ups at this point why change? However, for someone looking to buy a couple set-ups that will let them be more versatile it sounds great.
