Don't know what to tell you, outside my expertise. But I have good results using one of my old bamboo ski poles. What I need mostly is a fixed point to hold onto to orient myself. Then what's left of my balance takes over. That's a cross country pole that comes up uncomfortably to the arm pit. Sorta like a hiking staff but with a decent grip. The extra length over, say, a downhill pole seems to help. (Seems exceptionally weird to be writing this crazy You never see it coming and it seems unreal.)
