You are doing exceptionally well. Tall Telephone, Alderman and Novella ( one of the first released afila types) were ones I quit trying to grow in the 70's. Never could get a good yield from them in Viginia's New River Valley. Did have success with Freezonian which I planted on both sides of a five foot fence. Not as a vine as Telephone or Alderman, but a great yielder. Current status of Willet Wonder. In doubles rows at 12 inch spacing they support themselves pretty well.
