I'm dragging myself back into photograpy after a bit of an absence and picked up a dozen rolls of Rollei Superpan 200 for an IR project which is long overdue!

I've lost all of my notes so need help to refresh some info.

I've got a Lee 25 Red
Heliopan 695 (89B)
Lee 87 (above 730nm)

I reckon that the 87 filter won't be suitable for this film so will probably go with the 695/ 89B filter.

Should I set my hand held meter to ISO 12 for the filter factor?

Plan to shoot early morning, bright layer of white hazy cloud if possible to avoid black sky backgrounds. Overexposure preferred.
