Hi Kanno - big girls!! Appears you have a few N hogs. Got any green for these girls? Wow, big plants Kanno. Long stems. Sweet.When I supercrop I do the bend at the level of the rest of the canopy and then either tie it flat at 90° or put a weight on it to hold it at that angle. I use a binder clip attached to an open paper clip and hang that from the bent part.
That said, if it's a big branch it might want to fall further than 90° I support it from below to maintain that angle.
