best shift knob

Whjaxn17

Does anyone make a polymer/duracon shift knob that is weighted? The 90mm duracon Tomei knob for example...a steel or lead weight internally fixed above the threads(reason I specified the taller 90mm). I understand this still won't be close to the steel ball or piston ones, but living in Mississippi, heat is an issue to the point I don't really think a metal 1 is an option. I was just thinking if it were to be done with a taller style knob, the weight being placed above the threads would make it somewhat top heavy in hopes of at least somewhat offsetting the difference in total weight. You guys can fill me in on if I'm missing something...just a thought.
