I remember riding a friends Savage with buckhorns and I felt so disconnected with the front end. I like that hand position when driving a car but not riding a bike. Others will feel the oppposite.
But, after 5 riser designs, 3 different handlebar styles x 4 different lengths of the bars, I found the perfect setup for me- 6.5" risers with broomstick slightly wider than shoulder width.
Basically along the lines of what Srinath wrote a few posts ago.
