If wind buff is the issue I'm not sure if new seat would help. Any adjustment to passenger seat that would raise her might make it worse. If you're happy with your seat and she likes her seat, just not the air, my suggest is new x-large / wide windshield. I like the F-4 custom. Great product and customer service. If you also decide on new seat, I would also recommend Russell Day Long. Will custom build for both of you. Not cheap but a great product.
