Well I've been on the fence between HB vs SW for a bit, with plans on using the SW skid plate regardless of my crash bar selection.
Up until your post, I didn't see anything which indicated that the HB crash bars were not comparable with the SW skid plate. Obviously, there is an issue or you wouldn't be parting with yours. I just find it odd that I didn't come across something as my research has been pretty extensive.
I'll be ordering my SW crash bars and skid plate right after this. Wish I had known sooner, it would have saved me a bunch of time.
FWIW, I was leaning towards HB for the high radiator protection.
Sorry you need to sell, but thanks for the indirect 'heads up'.
