I agree completely.
If it's just tipping over, or a low impact fall, the plastic protection does the trick. Mine has topped sideways to the right (too much swing in getting on resulting in falling over

) and to the left as the sidestand I had just kicked out went back up

, resulting in me laying it down ever so nicely, of course witnessed by dozens of parked bikers.

. Alas, once a GS is leaning over too much, down she goes. Result : some minor scratch in the plastic protector.
If it's a heavy fall, you'll have damage to any kind of protectors anyway. I skidded on a wet mud covered road at approx 30mph, off she went, the plastic protector broke, but not the bolts by which it's attached to the cylinderhead. I chose to replace the valve cover, although the damage done was just a deep scratch to the surface. The valve covers can bear more than you may think.
BTW the reason that the plastic protection (MY '04-'09) supposedly doesn't mix with the BMW bars : they touch eachother on the left side, the LH side cylinder being more to the front. The 2010 plastic protection is different, perhaps to make the combination possible.
On '04-'09 models the tight fit looks like this :
This was in the Pyrenees, so I thought I'd better be on the safe side. Nothing happened, of course.
Home again I took the crash bars off; IMHO they're butt ugly.
