About safety precaution step 3

Should I use the 90DNS as well with OFW or just CFW? What I'm planing to do:

1. Keep using OFW to play original eshop games with sd-card A. Sd-card A contains only games downloaded from eshop.
2. Use CFW to play PSPPP emuator games sometime with sd-card B. Sd-card B contains all CFW(emuMMC) things.
