I love this fork. I mounted it on a Yeti sb95 carbon and kept it at the 140mm setting even though Yeti specs this same fork but at a 120mm on the stock sb95. I haven't noticed any penalty so far in terms of climbing or bob, and the fork makes descents just insanely fun. Whether bombing through a rock garden, or taking a few feet drop, it feels incredible smooth and stable.
In my opinion, the CTD function is just enough to be able to control the fork depending on what terrain you're riding, but not so many controls that you'd rather just ride and not change anything. I usually hover between trail and descend, unless I'm on a long fire road climb, where I'll set it on climb.
