I purchased a Surly LHT complete this spring and switched it over to Trekking/butterfly bars. I like the many positions and I feel that they are far more comfortable then drop bars. I purchased Paul Thumbies to mount the Shimano barend shifters on the top of the handlebar. I also purchased a set of levers that work with either cantilever or v-brakes. Covered the bars in cork grips and cork tape. Best bar setup I've ever had.
Here are some picture:
