To answer your original question, I have the same screen, the Wide-XL CalSci, on my '10. There is a big difference for me at 6' tall, versus the medium calsci standard width. The wide xl gives me a nice pocket, no buffeting, no back pressure. Makes a big difference on mornings like today when it was 19 degrees. There is less wind on my hands too, which is what I was hoping for.
I can look over the screen if I sit up straight, or look through if I sit relaxed.
The only downside is that with 2" bar risers, the screen hits levers on both sides at full lock. Not by much, but it will apply the front brake, so you have to be careful.
