It's not a synthetic fly. It's share risk downside and the strike width of the backspread, less the debit, plus the share gain, upside. It's not bimodal like a fly (always long delta) and has D1 risk downside. There is no point in a "repair" strategy if you flip deltas upside.
It's what should be added to the Wheel. Assigned on put -> solve for exp with zero outlay on short backspread -> goal to assign out of position at max gain as all contracts and shares cross above 20 (max gain) -> short put to open a position.
The Wheel is still dumb.
