Experience
I would've thought that the safety of this would hinge a lot on the experience of the pilot in IFR operations. Obviously a pilot who has 2 or 3K hours experience in single pilot IFR ops will be more accustomed to one who's fresh out of an initial issue, confronting some real trashy weather for the first time, rather than the hood and in an aircraft which he/she has relatively low time on type...and most probably a fairly complex one at that.
Fair call?
