If this film is a modified APX100 it might be the closest thing to APX100 we have today.
Personally I'm not interested in APX100 (too grainy for my taste) and the need to use the special developer to get the claimed advantages is a minus for me.
If the (claimed) finer grain is achievable with standard developers like XTOL, I might test it and see if I like the combination of image and price.
