Threadless are harder to adjust for height, but you can, it's a matter of putting spacers on the steerer tube, either below (to raise) or above the stem (to lower).
As for the weight of your Columbus SL framed bike, its like 80 ounces. Even with very light tubular wheels, without serious use of drillium, that bike can't weigh under 20lbs. CF bikes (with threadless headsets) that weigh 15lbs plus or minus are common.
By the way, I have a 1989 Paramount OS, lugged, hand silver brazed frame. It's a great bike, and I still ride it occassionally , but by modern standards its heavy. The frame itself is only a pound or so above a typical CF frame, but the steel fork with a steel steerer and a quill stem is like a boat anchor compared to a modern all carbon fork.
