So what we're saying, is both protect the sides of the cylinder, and both are effectively trashed after a slide (unless you plan on keeping the hideously disfigured covers on after a crash).
Can we just remind ourselves of the ask here, which is covers under bars. If I didn't have crash bars, I'd most certainly go for x-heads. If I had crash bars, I'll go for wunders for the additional protection. Aesthetics are an altogether other matter, but the WAMs tend to look a bit agricultural, especially after a couple of years on a bike (they fade). The wunders look smarter and will do more than xheads (by protecting the front of the cylinders) if you are running bars.
I’m just not sure why you think the Wunderlich ones offer more protection.
The x heads are more flexible, the wunderlich ones are hard plastic which means they break on impact (an issue that machine art had with their first x heads and have since addressed it).
On the 1250 shift cam the x heads cover everything necessary and even replace the spark plug covers.
