My '06 Nomad (since departed) had the stock windshield and, I replaced the stock lowers with a set of custom wide lowers from Chucksters customs http://www.chucksterscustoms.com/Home/Products
", cost $48.00. The difference with the custom lowers was considerable and provided an almost total buffeting free ride. I had expected an improvement but, the custom lowers far exceeded my expectations. They also allowed for cool/cold weather comfort, which greatly extended the riding season (which was my primary reason for purchasing them).
I had also added a set of risers which resulted in the windshield having to be set to the highest position, which was fine by me. Added info: I'm 5'10" tall.
If anyone's interested, I have the custom wide lowers and also hand guards (never used) for sale.
