IME wrasse and all fish can be jumpers under the right conditions. Things that I've personally noticed that can make fish more prone to jumping is the presence of a bully, and tank height/size I believe can also have a factor. That being said I wouldn't trust any wrasse completely without a top, as I have had some carpet surfers before...
You can make a screen that is below the top of the rimless tank. I do it on my rimless. It is almost unnoticeable. I have all sorts of jumping fish and not a single loss.
Cakeman, that's a great setup. Very nicely done!
