I’ve had problems with using MLD aluminum pole jacks on Komperdell (my regular poles) and Black Diamond (used occasionally) carbon trekking poles. The pole tip is always inserted at a very slight angle. It never fits just snug and flush. The pressure on that slight angle is increased when the whole pole itself is angled, as is very common with monopole shelters where the angle affords greater convenience in the living space. This can result in a bent pole tip and, under more extreme circumstances, a broken pole tip.
Whenever possible, I’ve given up using pole jacks at all, preferring to use a rock instead. But I need one for a Mid that goes slightly higher, beyond the reach of a trekking pole + rock. I only use one pole in summer, so combining two trekking poles together isn’t an option.
Strangely, I haven’t seen other people raising this issue, so I’m wondering if the diameter of the pole tips on other brands isn’t a perfect match?
Is this a brand issue? A sunspot issue? An antimatter particle exposure issue?
