Washing out of one 121 initial could be a fluke, washing out of two is a trend...especially when the cause of both is poor instrument skills and/or being behind the plane.

I would agree that a 135 job would be a logical step at this point...something like Cape Air, Air Cargo Carriers, Mountain Air, Ameriflight, or the like. Not that any of those would be "easy", but at this point it sounds to me like the speed of a swept wing jet is causing major trouble and a twin piston or turboprop could be the ticket to successful transitioning.
