WTT 165/137 for 150/125

I have a pair of well used, but in fine working order, KH Moment 165/137mm cranks and would like to make a straight up trade for a set of 150/125 cranks. You send me yours, I send you mine. I’ve pretty much settled on the 150’s for muni and would like to be able to switch to something shorter for occasional road riding.
