Note that the old Kodak Infrared film Andy spoke about was a 135-20 
configuration, with a very long dummy leader AFAIK. This was one of 
the first Kodak IR films, not nearly as sensitive as the current one, 
and not called High Speed either! 
This difference in both speed and spectral sensitivity makes one wonder 
whether replacing only 20cm will do the trick....
Considering that one needs to add more dummy length, it makes sense 
to cut the film in half, and probably end up with about 20 frames on 
each half....you gain the entire length of the original leader!
