I opted for the ProTaper ATV High bend. It's higher than stock, but not as high as the Raptor, and has a milder sweep. As expected, it was an easy install with no cable length problems. I drilled the bar in order to interface with the control's plastic anti-rotation pins, and installed a bar-end insert kit (G2 Ergonomics Nylon Handguard Bar End Mount), which required that the inside of the bar be threaded with a tap. Once threaded, nylon inserts are screwed into the bar, and the provided screws secure the original equipment bar-ends into the newly installed inserts.
What a huge improvement! Before the swap, the severe sweep gave me a terrible case of tennis elbow, and I had reached the point where I couldn't stand to ride anymore. After the new bars, the tennis elbow quickly went away.
Thanks to BarkSlayer for the laquer thinner tip. The ATV High graphic has always annoyed me, so I'm off the garage to make that go away.
