well, I decided to wait (ie I procrastinated
). In the meantime, I got a call from Heli saying that someone had returned their bars because they didn't want them and asked if I was still interested (talk about customer service - holy cow, kudos to them).
Got them and it took about 40 minutes to put them on the bike. Only trouble I'm having is that the brake line is hitting the fork tube when I try turning the lever down - need to mess with that some. Other than that, it's noticable that they're higher and further back. I'll use them for a while but I think I will eventually go with the LSL kit because I want to be even more upright. I'm still leaning too far forward and it hurts my neck more than anything after a while.
Moral to the story though: Heli has kickass customer service.
