I guess folks find a love for the tools. I never put much if any thought in my poles .. if heavy - well I guess that'll build wrist muscle. If lost, I buy cheap.
I gotta say I'm astonished at the high percentage of accomplished, enthusiastic skiers that do not recognize the value of well-designed, low swing-weight poles (and their wrist straps). With all that we spend and obsess over skis, boots, passes and travel, worrying about the cost of poles seems insignificant.
Ski poles can certainly also be used for fighting, so it's inadvisable to advise anyone who's skiing purely for the joy and rush of sliding downhill that what they are doing, or not doing with their poles, could be improved. There's already a bit too much gritty pole-impole-liteness in thread.
I sure like being able to skate away from the lift as I click in my 1st-gen LEKI trigger grips, instead of stopping to wrangle my gloves thru wrist straps. They are only 25 years old, the carbon chipped up enough above the basket from ski edges that I really ought to get new ones, eventually, but now they have sentimental value. They were valuable as trendy crutches (with rubber tips) to gimp around my workplace as I recovered from ACL surgery, many years ago.
