I actually just got my shift knob in from Lathe Werks and it's amazing. The weight is 465 grams which is a little heavier than the M1 Abrams from TWM. I got the gun metal finish and boy oh boy shifting with this thing is a treat. It sits really low since the threads don't start until about halfway into the shift knob. Customer service was A++ as well so if anyone wants quality and has the extra penny, get one from Lathe Werks. The owner does everything himself so you know you are getting something good.
