I have a Ricks Voodoo knob. Totally love it.

 

so if rick could make a ciuntersunk knob at ~440 grams, he'd get alot more sales, including mine

 

yep. i have the ricks black pearl voodoo knob. great feel. love how its countersunk. wish it was heavier. tmw might be my next choice.. lighter knobs are just harder to shift super fast imo.

 

^IMO a heavier knob doesn't shift "faster", maybe smoother. The physics of inertia would indicate a lighter knob should be faster than a heavier one. Unlike cars with a lot of linkage slop, I find the S2K trans to be precise, and careful, but quick shifting with a light knob works best for me. I'd down to either the Mugen "dildo" (which is a little too small but I like the shape) or the Voodoo (which is a little too big).
