Sorry for the delayed response! Tried replying from my mobile but that didn't go so well.

@Roger Cole: You are right. I actually thought that the fuji instant film image area was much smaller as I saw a video with someone using it with a Hasselblad, I just figured that only a small area of the sheet actually would develop an image. I'll give the mask a try, and see how well it suites me.

@wildbill: I agree about the experience, and your suggestion about using a digital camera is a sound idea, but as it is right now, I want to keep my DSLR out of the equation for the time being as a personal preference.

Again, sorry for the delayed response, and thanks to all for taking the time to give me some advice!
