I personally think that a first class medical should be a requirement for single pilot part 135 ops.
I fly with some old geezers who look like they are ready to keel over any minute and yet they fly single pilot IFR.
Dangerous in my opinion.
It is not an FAR requirement for part 135 PIC's to have a first class medical but most insurance companies either require it or give very significant discounts to clients who's pilots have one.
