MRA-Xcreen Update -- Wing Position and Air Flow

Just a quick update here.  I had a chance to take the bike out for a couple of hours today and play with a number of different positions for the wing on the X-creen.  I had originally been riding with the support arms pretty much straight up 12 o'clock with the top of the wing angled slightly backward since this is how it appeared in the pics from MRA.  This worked pretty well, and after installing the spacers, it even seemed to work better.  After several starts and stops to test various positions, I've now settled on having the support arms positioned so they are pointing directly forward with the top of the wing angle back so it's almost, but not quite, parallel to the primary shield.  It's probably about two clicks away from being parallel.  Sorry, I didn't take any pictures, since it was a trial-and-error process.  If you want a picture of the final position, leave a comment, and I'll go take one and add it to this post.

It was fairly windy today, with the winds blowing out of the south, so I was able to test the position with and without a headwind as well as with crosswinds.  This new position seems to push the air high enough that the air intakes on the top of my Shoei RF-1000 can catch it, but it leaves the helmet itself alone.  I'm not sure, but I think this works better than the original position due to the wing being further forward.

I have also come to the conclusion that the primary source of any buffeting is now the mirrors.  Installing the mirror extenders helped tremendously, so I may experiment with angling the mirror stalks in a little more to see if that helps.  I also considered buying some Saeng Micro-Swirl Generating Edging and putting it on the front of the mirrors to see if that helps.  Then again, the temperatures are quickly ratcheting up into the 90s, so it's probably worth it to have a bit of wind for evaporative cooling.

UPDATE:  At the request of Mark Collins, I took a picture of my current wing position setting for your reference. As you can see, the support arm is pointing directly forward, almost parallel to the ground.  The wing is angled at about 45 degrees from the arm, which gives it a little upward angle relative to the primary shield. In case you missed it in the original X-Creen post, I'm 6'-0" with a 32" inseam, so your mileage may vary with this setup.
