S-H gliders can be challenging to reach everything properly. Are you short enough to move forward in the cockpit? Often a pad(s) behind you will improve ergonomics dramatically. One of the first flights in my Ventus B I could not put the gear handle into detent until I loosened my belts.

I use the tubing extenders on my radio in my V2a still, but can reach everything else in the "A" cockpit. In a "B" I feel like I am in a cavern.
