Sounds like I have the same set up that you do. I had trouble getting down in the car with both of the clamp on pads, so I only used one. What I
do have is the double leg brace support that you dzus in at the front of the seat. Out of the 4 times I have tested it this year, I only banged my knee once. Here's the link to that:

Last time I talked to Brian Butler, he said he had something new in mind for the knee guards, but I don't think it's ready yet. I will see him tomorrow, and I'll try to remember to ask.
