Even if there were no weight penalty I would also pass on anti-shock.
I used a friend's poles with this feature and found them rather annoying. I prefer a solid pole plant with the immediate tactile feedback that confirms a good, solid stick. That boingy-bouncy feeling from anti-shock detracts from that.
But I guess I could get used to it if I had to…
However, do not dismiss the value of very light poles such as GG LT4 and the like. By UL standards, 1 pound is actually quite heavy for a pair of poles. I did a lot of experimentation last spring, summer and fall to see what really suited my personal preferences for UL backpacking. Tons of experimentation using them uphill-flats-downhill, strap and strapless, etc, checking time/distance, noting hand fatigue, etc.
I settled upon the Black Diamond Ultra Distance (carbon, 120cm fixed length) with the straps and connecting hardware removed (sections glued together with epoxy). They weigh 4.3 oz each, are plenty strong for me, and I just love using these things. Turns out the 120cm length is also perfect for pitching my shelter (zpacks Duplex), so this is a dual-use match made in UL heaven.
