Now it has 45 miles? Is it snowing in DFW? Are you feeling ill? Are the streets closed? We will expect another 400-500 by weekends end.

Congrats.

At 5'7" and being in a long riding hot weather city, I would not go passed an 11" or 13" shield, preferably the 11". You are going to still want some air blowing on you during May to September. Also consider Baker Hand Wings for more flexibility in ventilation all year. Wingstuff has them for a great price.
