I use promenades on two of my bikes and I use those bikes more than any others (I'm a messenger and spend many hours/day in the saddle.) I also have hand and wrist issues, which were practically eliminated when I switched to the proms. On one bike I have the bars jacked up to saddle height with the bars angled down toward my waist. Gives the perfect neutral hand position (for me). They have the added benefit of being:
1)relatively light
2)relatively cheap
3)Nitto, therefore well-made and gorgeous
