Chenner…
Solved the issues on my 20.1. Dennis from Factory Mad made me a rigid nylon Velcro strap to replace the elastic knee block stock strap. Increased stability with the floppy knee block, keeps the pad face from leaning forward or flopping down in a slide and eliminates the boot break gap
Sliding and responsiveness improved drastically. $20 for the straps. I highly recommend this mod or ordering the behind the knee leather strap. Awesome customer service from Dennis
