Well I'm an engineer (I guess that's close enough to being a scientist) and am always doing experiments (developing new products) although generally always for other people. Yes, lots of different opinions and I guess the only way to find out is to try it. Not sure why there is such a difference of opinions on the subject - pretty much the same if you look on the web - some people claim better performance and others worse performance. And yes, I guess the amount of current being conducted at that voltage is pretty small anyway.
