Anne, I actually use my straps all the time. I do NOT use handles at all on my poles. I set the pole height to about 43″. This is a bit high for me. Then I set my strap length to about 2″ low for me. A simple twist in the strap will shorten it enough to make it perfect. Going up hill, I usually have the pole behind me so, I may drop the twist. Going down hill, I just use the pole with my hand over the top, relieving pressure from hopping down rocks and big steps. A simple “pencil” grip is enough to move to the next spot. I rarely grip them hard, this can leave your forearms very tight. I really hate having to carry anything while hiking, even a staff. Except going down steep rocky terrain, the strap takes all the weight naturally and picks up the weight of my arm/shoulder sway. Corse, these are light 4oz poles. They work really well as shelter poles.
Light poles make a HUGE difference. I went through two pair of Komperdels at around $80 and and a pair of Lekis at around $120 before I started making my own. The tips were constantly snagging on stuff, then, breaking/bending. Just the wrong size even after removing the baskets. And, they were rather heavy at about 6-7oz each. I only ever use one, my other hand needs to be free to grab things, drink, eat, etc while I am hiking.
I have been known to switch hands on longer uphill grades, though. That is the only place I miss having two. I do not use a standard tip. Just a bolt tip. Hard enough to bite on ground and wood, soft enough for rock. Yes, it wears slowly…change the bolt once every couple years. Looks like a paper spike except shorter.

Note the wider shoulder near the pole tip. It actually supplies better support than the more conventional tip on the right. The somewhat longer bolt-tip means I can plant it into the ground and expect it to stand up when I need both hands or at rest stops. This is all epoxied together and has a diamond wrap of nylon .75mm line, also epoxied, around the lower 4″.
