Yes, a bit. I use 35mm, 120, and 4x5. The fact is 120 would serve all my needs. Hell, 35mm with film like Ektar or Velvia probably would too, there is plenty of resolution there really.

But yes, I could easily simplify down to 120, very easily in fact, but I just like trying new things too much. I had sworn off 35mm a couple of month ago, but now I'm eyeing up a Voigtlander Prominent...
