Just to clarify, if you have a balltop for a JLF, you are gonna need a JLW-T. If you get a JLW-U you will find that the shaft is too thick to fit the balltop. AFAIK, there really isn't any difference between the two models other than the shaft.
Ultimarc sells longer shafts for the JLW. It is marked as their Ultrastick 360 long shaft, but it will fit on a JLW. (Their J-stick balltop is a JLW-T) Make sure to get the shaft for the T and not the U, they have both.
You could also get a JLF, but you would need to heavily modify it to make it good for pacman. I only bring it up because some people get a kick out of modding sticks, and the JLF is an amazing, quality stick that is really fun to change around. You can find hollow extra long shafts for LED lighting as well. With no mods, the JLF is about the polar opposite of what you want for pacman though.
