My apologies for bringing up yet again a well versed subject yet after reading what I could find on the subject I have not found the answer I have been looking for. What size do I need to consider if I want to duplicate the height of the OEM windshield in the lowest position with the Cee Bailey #2? Is it the -2 or the -3? Or is it the -4? Looking at their web site I haven't found that answer as well. Based upon how I sit in the saddle the OEM windshield height is perfect for me in the lowest position as I love to have a clear line of vision over the windshield.
