Another Option, Trekking bars , more places to move your hands around onto,
I use a 'grip' that is across the Hole of the Figure 8 bend , sometimes,
which relieves the palm contact entirely for a little while ,

double wrapped with padded tape..

I'm ordering a set of Ergon, CG3 I think, they have a long integrated Bar end.

Put them on my Bike Friday, as the trekking bars, as is, won't split for BF packing..
