The big reason to use the strap that way is to avoid tearing the ligament in your thumb. I’ve seen someone do that who fell over basically standing still. Had the strap over the thumb, fell on the pole, tore the tendon.
How in the hell did you break them?
I have had three pairs of Goode carbon poles in the last 30+ years, two of them are still in service
They broke below the basket. The carbon fiber tube cracked, opened up, the metal tip fell out. Goode replaced that section with a plastic piece below the basket, kind of like Swix poles. That sort of ruined the lightness.
They next pole broke an inch or two above the basket.That’s the achilles heel of carbon poles. If you hit them with your ski edge when skiing, they get nicks there making a very weak spot. Late season on a cat track we were playing ski polo, hitting a crushed can down the path. On one wack the whole bottom of the pole went flying.
When I first got them, I thought the adjustable length on Goode would be a plus. Allen wrench to loosen, then turn handle. Adjust on the lift! Then you find out the thread for the grip is something like 32 threads per inch. So that’s 32 turns of the grip to change it one inch, times 2.
That’s the problem with just having an engineer develop products.
