Thanks guys.
I ended up buying the orange ones that Bgnome pointed out, but am a little unsure whether the color will be okay with my plans. I suppose if they don't work I will just have to put them back up for sale on ebay to recover part of my expense.
I had also seriously looked at the robotron sticks at arcade shop as a possible solution before, but these will go into a metal CP for a cocktail cab and the robotron shafts look a little longer than the standard WICO shafts so I am afraid I'll end up banging my hands into the top glass unless I machine them down.
In the meantime, I will have to break out the dremel and see how much of an improvement I can achieve with the existing sticks as MinerAL suggested.
Thanks for the info guys.
