The problem with saidin around Ebou Dar seems like it can be attributed to the use of the bowl of winds. After all it did draw on saidin. But Saidar is also unreliable in that area as shown by the damane who was crying because her channeling backfired on her. Rand's seeing double when seizing the source could possibly be on account of the dual wound on his left side. Either that or Lews Therin's Id is becoming stronger in Rand. If that is true, Min's viewing of two men merging into one should solve that.
