Add me to the list of people with both shields. I have an 08 that I bought used with the larger shield. I am 6' with a 32" inseam. The larger shield is very noisy for me in the down position. I can find a spot about 2/3 of the way up where it gets pretty quiet. I bought a short shield to deal with the heat this summer.
After reading the comments I may need to try a laminar lip on my tall shield. Are there any secrets to mounting location or anything else?
