The factory teaches to use the rudders to bring up a low wing on landing, but the VGs make the ailerons much more responsive so that you don't necessarily have to.

Since we got most of what we wanted with the VGs, I haven't elected to install the fences, though I made some off of the templates that I got from Chris Martin's plane (Klaus Savier worked with him to get those sized for the Velocity).
