Class 1 medical for IR, even if attached to a PPL?
That would kill it for a lot of people. So far to my knowledge you needed an audiogram and some additional requirements for the Class 2, but to get a class 1 medical would be the show stopper and also again make the IR impossible to achieve for a lot of folks.
Otherwise, I have to say I like what I am seeing. A lot actually. The EIR as a first step, fully acknowledged for the "full" IR if taken later, the IR theoretical stuff reduced to some new level e.t.c. sounds almost too good to be true.
