Kinda going against the opinion thing here, but I have always thought "who cares what others think" and my reasoning behind it is that it is my tank and I look at it everyday, and others will occasionally see it. yes it is good to see what others think, but at the end of the day do YOU like them.
In my opinion, if you aquascape your tank as to what others think looks good, then you are not in the hobby for the love of it.
Just my two cents worth, and if you come to the conclusion you like them, then go for it, give em a shot, you won't know untill you try.
