If Egypt is uncounterable, Germany could send 3 tanks to Ken on G2 and land some planes in Egypt, putting the SAf IC in a big bind. For a SAf IC, I like EM’s setup more (it’s floating around somewhere in the Revised section).
If you can counter Egypt, I think a SAf IC is not worth it I think. Landing in Alg, putting your planes in WRu and eliminating the German Med fleet on UK 2 is a better way of securing Africa if that’s what you really want.
