Large diaphram capsule options

I'm trying to find some info on what capsules will work with a SE Z5600a II.  I was told that the RK-87 from Microphone-parts would work, but I figured if I'm replacing it I'd get something a little more high end. I've been looking at the Peluso stuff, since they're not too expensive and seem to get good reviews. I just don't know what to look for. Are there specs I can look over to see what's compatible, or any info that can help make an informed decision?
Thanks if anyone can help

A K87 style capsule will give you some treble boost, because this capsule needs HF rolloff due to the HF pre-emphasis in the design.
I would go for a CK12 style capsule, or maybe a K47 style capsule, if you like some more 'presence'.

Thanks for the advice, probably going to go with the 47.
