Contrails for other aircraft online

Hey guys,I have been flying online for a few years now and have never seen contrails behind any of the other pilots aircraft. Its something I feel would add a lot of realism to the online experience. Here is my question, I have found two products for contrails. One is Contrails Pro by FlightSim Tools and the other is a recent release called 3D contrails by Supression Flight. Does anyone here use either of those? I am curios as to whether the 3D contrails by Supression flight works with online flight. I know the Contrails Pro do but have also read of frame rate hits and not realistic looking contrails. I hope someone here has used one or the other and could help out on a potential purchase! :)Thanks!
