Well, my fehling bars arrived and I finally mounted them. (I updated my avatar so you can see how it looks.) While I agree that it offers less protection than I would have liked, IMO it's better than nothing. At least now if I drop it, there's a chance no serious scratches will occur.
And since my order include the rear bars, I guess I'm no longer looking for sidebag mounts. When I was writing to Fehling about my order, I asked them whether the mounts would fit on the FSC - and, if so, to substitute the mounts instead of the rear bars. But since their reply was negative, i just went ahead with the original order. A mistake, I think. I was tempted to get the side mounts and send them to Dennis to see if they could be adjusted (fairly) easily. In any case, I really don't have a big need for the extra storage.
The bars are smaller than I had hoped for. The mount points seem to have been well thought out, though, and the hardware contains longer replacement bolts and spacers. It took me longer to install than I imagine most of you would take - but it was really fairly straight-forward. I didn't even have to remove the Nelson Boll Leg Deflectors. The side bars went right around them. (Although I did have to trim them near the top. No problem.)
In any case, I like the finished look.
