I like my old DIY Zhanchi with torpedoes. With an exceptionally loose setting, there is a risk of the edge piece torpedo grabbing another edge or corner piece at the transition and twisting out and spectacularly flying across the room. I have since developed a feel for that hang-up and know not to continue twist at that point. Most of my practices are for BLD, so speed of execution is not my main main focus. Besides, I learned from touch typing that a steady rhythm contributes more to a good score than bursts of amazing speed.
What I have found, is that pulling the corner-edge-corner 1 x 3 block away from the center -- if the center is loose enough that you can generate a "click" -- that center is adjusted too loose and needs to be tightened. I find that if I tighten the centers just to the point where I cannot produce the click in this manner, the cube is still very loose, but the torpedoes then are much less likely to foul on the transition and twist out.
