So I have a bunch if Rolllei IR film. I haven't been able to afford an IR Dark Red filter.

I have 2 regular red filters, one is B+W the other is Hoya, can I stack them to get a better IR effect and if so which should be inner and which outer?

Any other suggestions? I'm going to the Grand Canyon and want to take advantage if them of possible...
