For my money, I would go with the HT bars. I had the givis, and they didn't do too much good in the only get off I've had. They might have helped minimize the damage, but I was still left with a twisted, leaking rad, broken fairing, and bent Givis after an (unimpressive) fairly low speed drop in sand. For the first year I had them, I was quite happy. They added a little vibration @ 3500rpm, but they also gave me a somewhat comfortable spot to rest my legs while on the freeway.
Honestly, instead of more crash bars, I'm leaning toward the Safari or IMS fuel tank once released. The older tanks seem to do a decent job protecting things, and Safari says the SW-Motechs will fit with their tank.
BTW, I've had good luck dealing with Sport Tour several times in the past.
