The woodchipper has a verywide top and the hoods are pretty vertical.
The gary bar is useless for riding the hoods. Its 100% a ride in the drops bar. The soma is very similar to the gary bar with the levers moving very horizantal.
Like I said, I'm biased as I love dirt drops and LOVE the woodchipper, and pretty much hate 'road' bars. I have used it for a 4 hour ride on trails and it was awesome. I can ride on the tops, hoods, bends and the long flare. Great for climbing and decents as your hands are 'wedged' into the drop and don't need a firm grip to maintain control. The woodchipper is IMO perfect for long rides.
