These look exactly like the ones sold at costco for much less? also no anti-shock? Is that needed?

They have poles at Costco, currently $70 for 2 pairs (4 total poles) but the poles being sold are the "normal" poles at 8oz per pole rather than the ultralight poles

What is the difference between the neoprene and cork handles? Not sure which to choose, they are the same price

Cork has the following benefits: 1. Cork is a natural at reducing bacteria. Get a splinter, blister, cut and cork will provide added protection, 2. Cork will slowly imitate the shape of your hold ensuring a better grip, 3. If it gets dusty or gritty during use, I use an old toothbrush to "sweep" particles away, 4. Due to a latex intolerance, I avoid neoprene, 5. Neoprene collects/absorbs smells, 6. Neoprene may not show discoloration due to it's color, but it is very porous. Hope this is helpful.

What is the primary difference between standard carbon fiber and 3k carbon fiber? Is it simply a strength related difference?

Yes, it's a strength related difference and more. 3K means there are 3,000 strands of carbon fibers in the tow (the thread of CF that is then woven into a fabric). They are extremely thin, huh?! 6K or 12K might seem better, it is easier to manufacture using a broader tow but it is a heavier weave. This is like comparing silk vs cotton cloth. One is soft and flexible, but the other might be stronger, more durable or stretches better. The trade-offs for trekking poles are flexibility, shock absorption, strength and weight. Many trekking pole manufacturers are moving towards 3K as the right balance. That said, I'm not an expert but learning about it.

does this pole have anti shock feature? what is the difference between your 29.99 dollar pole?

No anti-shock feature, but I didn't want one. These poles have same overall weight as a set that costs $189. The $39 set has quick lock system that I prefer instead of the twist lock system on $29.99 set. These are cheap enough that I don't worry about babying or breaking them.
