Thanks for the compliment! After checking out the linked thread, I must say that I love my current 3 710's (my combo-edge sold and the BK gifted) and can't say I have any problem with their closing action. My 2 D2/G10's both free drop easily when properly lubed and tuned, and the re-scaled -1401 drops well past 90° when closing and is easily finished off by thumb. I always use two fingers to pull sliding bar locks, the blade hitting my ring fingernail before my thumb takes over. The D2/G10's will close all the way using just my thumb on one bar stud, but I've always felt that using a single digit contributes to added strain on a single Omega spring and will contribute to its breakage.
I will say that some BMK AXIS lock knives do have a very narrow sweet spot for balancing blade play with free closing action. A little bit of occasional tinkering is no big deal to me, though, and part of the fun of the hobby.
