I preferred the round thumbscrew from my first PRS bipod even though it was on a shitty Amazon/Chinese arca clamp (on RRS Harris adapter). The ckye pod's triangular thumbscrew was just too "course" and required putting my whole hand into it versus just rolling it with my fingers. I found a solution using a 3/8" x 1" x 3/8" nylon spacer from my nuts/bolts stash. I had to drill out the center a bit to get it to the point where I could hammer it on. Threw on a little skateboard tape and now I'm very happy with it. Best of both worlds. I naturally go for the triangular knob when I need to torque it good and use the round spacer for faster fingertip adjustments. It doesn't stick out any further than before.
