Canopy
Another solution is to shorten the upper slide rail or put a notch in it to where the UHMW slide will come up off the rail sooner. Kinda hard to "splain" but if you slide the canopy back and forth you will see.
Cut it or notch it just aft of where the rear slider comes to rest when the canopy hits the back stop. IIRC, there's a screw at the very end of the strip, so I notched mine. Wish I had a pic.
