stick shift

I want to get a new shifter knob for my 98 ranger manual and was wondering what you guys have. I might get a .44 grip. What do you think?

its just started to happen, its very annoying riding 60 down the road and all i can hear is that darn stick rattling. any ideas? oh and another thing thats happening is the truck wants to buck like crazy when i change from 1st to second, to third. it stops bucking after third
