You don’t say the weight limits you are looking for. Using one trekking pole, my weight is 7.5 oz. For me, a second pole is excess baggage; but this is not so for those who need a second one. Were a second pole needed, I’d go much lighter to keep the weight around 7.5 oz.
Found a Yukon Charlie ‘carbon’, a lower priced brand, 2 poles for $50, that showed metal for the bottom two sections, where breakage is more likely, due to the pole getting jammed in rocks, and similar breakage issues that are more prevalent in the lower parts of the pole. This was a deal maker. The top section was all carbon. Don’t know if there is carbon under the metal lower sections because would have to damage the poles to find out.
Also prefer telescoping sections, because with the flick-locks especially, the pole is much easier to collapse and store behind webbing retainers on the sides of the pack. Ditto for day packs as well as trekking ones. The separating fold up poles like Black Diamonds are deal breakers because they are clumsy to stash. The telescoping poles also allow exact length adjustment, great for mids and similar designs, or just propping up an awning.
But the grips on the Charlies were junky foam, so had to be replaced with a much better extended grip from a European ski trekking pole. This requires a huge pot to heat water and remove the old and new grips intact from their poles. Read about it on BPL, but it was a challenging process. The long stiff foam grip was a must to be able to choke the pole. This is the kind of grip:

The lower sections are not visible because the pole is folded up. But the European grip has a long ribbed extension that is easy to grip when choking.
Also used to have a closet full of poles, but the Charlie with the new grip is all I use now. The second Charlie and the second European pole were saved to make a replacement if the first pole ever fails. Note the preference for a flexible tip covering the carbide tip, as don’t want to scar up the rocks so prevalent in the ‘Granite’ state. And with a little practice, the flexible tips work better.
So suggest deciding on the type, and weight of pole before shopping. Some of the European ski trekking poles can be bought in outlets for less than $100 a pair. And if you want all metal, no mods are required. Would not recommend an all carbon, as carbon comes in different layups, and it is perhaps impossible to check without damaging the pole. Not that some carbon layups aren’t very strong, but it’s hard to know what’s under the skin. Check the prices on filament wound carbon tubes from the major suppliers. Doubt manufacturers could profitably use the best carbon.
