Yamaha DTXpress/DTXplorer/DTXtreme

I will soon be replacing my stock DTXPRESS II cymbals with a couple of
visu-lites, but how do I know which are the right ones? I would like a
14" chokeable crash, and a 14" ride. Nothing fancy.

On the visu-lite site, and on drumbalaya.com there are SO MANY to
choose from. Like what's the difference between an FSR choke and an
aux choke? Which ones are right for the DTX brain? Is there a better
alternative out there than the visu-lites? Those Pintech Zenbals look
pretty sweet too. Are they any better compatibility-wise then the
visu-lites?

Thanks in advance.
