Yeah man, I really like that combo, but I'm think I'm going to go with the Speigler top clamp and bars(especially with a RDL seat). Big E has a thread on his. I also have many years of dirtbikes/motocross and I don't think those bars would hinder agressive riding ability on the Busa(should be even better!)
Of course that's a personal preference, but something to consider since the heli-bars and spacers aren't cheap. I've tried several bar combos and I'm on my 3rd seat in search of the perfect setup for ME.
I'm glad for the experience with all, but all that money could've been spent elsewhere too.
I know alot us are in out of the way locations, but I'de try hard to sit on someones bike with the ergo mods you think you want.
I'm also not trying to get this seat thread off topic, but seats and bars go together(and adjustable rearsets). It seems lately that quite a few of us would like our Busa's to be just a little more comfortable.
