I took my wind deflectors off last year. They were only partially effective as they are small, and were the type that had to be outside the sidescreen resulting in having to "open" them out to prevent the sidescreen hitting them on opening the door. The bolts mounting them had dome nuts that prevented them being moved inboard so they stuck out like jugg ears. I tried slimmer nuts but no big improvement.
There is a description somewhere of custom made diy wind deflectors/sidesreen that were effectively a "half size" sidescreen but fitted as per wind deflectors to the windscreen pillar, made from perspex(or similar) and shaped to miss the door and wing mirror for opening. Maybe worth investigating.
