How stiff is aluminum 4-4-4-6 aluminum SER wire? Adding a subpanel 35' away
I am working on cleaning up archaic (50s and 70s), by my standards, wiring in my basement (long house with three sections). Plan is to put a 50AMP (maybe 70AMP) sub-panel in the newer addition, which would eliminate about 35' of run for 12+ cables and bunch of j-boxes. Plan was to do 4/4/4/6 AL SER wire and do 70AMP sub-panel for future expansion... but now I am thinking SER wire might be too stiff for 3 90-degree bends (not in the same spot, just along the way). If it is too stiff, then I am thinking 50AMP subpanel with 6-3 Romex.
Thoughts?

I don't consider #4 AL SER as stiff at all. People run #2 and 4/0 AL SER all the time in residential work. What difference does it make how many 90 degree bends you have? You can have as many as you want.
#4 AL SER cable should be protected at 60 amps.

You bend it by hand where you need the bends. You don't need to be a gym rat to bend it.
Make sweeping bends, not tight 90s.
