I think the wind issue is about 75% lower and 25% Windshield.
I have a Gust +2" and lowers. The WS helped by maybe half of the upper portion of the problem.
The homemade lowers helped by at least half of the lower 75% portion. My wind is much much better with this combo. I still may consider the new forged bar lowers from reading the thread on here but NOT needed. I may get a little additional benefit of wind management but mostly for the speakers.
