I know the point you’re making but seems to me that black on red and white is quite prominent. And white on the away shirt shouldn’t need a plain back.
Sunderland and Sheff Weds are both shown on this thread as having striped backs, but we’ll have to see what they look like on taking to the pitch.
For me it’s quite straightforward, stripes on the shirt front and back. Or abandon stripes and go for the Rank Xerox, Halves and occasionally the sash.
