I bought a Disc Trucker fork and installed it un-cut on my Steamroller for similar reasons. I am now working my way down through the spacers to find the lowest height at which I can ride comfortably. The bike looked pretty silly to start with, but was surprisingly stable despite the long steerer tube. A long steerer tube is a lot more rigid than a fork with a stem extender on it. I know; I tried that first. I will cut off the excess steerer when it gets to be more than an inch above the handlebars to prevent impalation. I also use Ergo grips on Surly 1 x 1 bars, which is a very comfortable combination for me. My pain has disappeared and my view of the road and surroundings has improved greatly.
