Personally not in the habit of changing my knife clips to DC but people should buy, what ever they want for their dough, even if Im not a fan.
On some knives, DC seems counterproductive. I bought a Yo2, which came with a DC clip; why one would equip a SD knife with a DC clip is beyond me but then I dont carry a knife for SD hence shouldnt really care one way or the other.
I yanked the DC clip anyway and also exchanged the scales (coyote instead of black G10). It makes for a fine cardboard killer, which is fairly easy to get out of the pocket.
Edit; added pic of aforementioned knife. Yo2 with coyote scales instead of black and 'bronze' MXG Gear titanium clip.
