On the topic of Vision3, ECN2, Kodak's sales strategies etc. there are several threads that you can refer to. Let's keep this one here focused on Harman Phoenix. On that subject - if you want to control contrast and saturation of Phoenix, the most feasible route is to give sufficient exposure so that important shadow detail is recorded, scan the negatives in such a way that the entire tonal range is captured and then adjust contrast and color to taste digitally. Whether you develop in C41 or ECN2 really doesn't matter if you follow that route.
