I'm curious, does the pylon really make that much difference? It's only going to move the attachment point up about a foot or so, right? I do understand that it gives the observer handholds but does it really make that much difference for the actual tow rope connection?
I did one and posted here on the forum. Did it to my RXT with pictures and everything. I did have to use a hole drill. First used good blue masking tape, then drilled thur.
Use the search in the upper right. Pylon install.
