Or, how about a slick custom Chinese titanium stem? Don't know the cost but can't be too exorbitant. Cleaner look, space for accessories & Ti might give a smidge of shock absorption. BTW, seems a bit ironic that LHT/DT which is designed for long-distance touring (& presumably a semi-upright avg riding position) requires leaving lots of steerer tube & spacers. I ride more leaned forward than many tourers plus my frame is max size I could use yet if I had the stem at lowest possible height it would be in time-trial position.
