It doesn't really matter what anyone else thinks, although it's nice when compliments are made. I like the look straight on looking at the side of the engine, but the ones on the windshield, not so much when being able too see the entire casing. They are too long and just look gawdy to me sticking out that far.
If it were me, I'd cut the casings down so that they are just long enough to cover the nuts they are over. You can easily cut them down shorter using a tubing cutter.
