Hello! You missed my point. I don't believe I promoted DR. I believe I wrote that if you don't have the wherewhithall to maintain SA neither a GPS nor DR are going to be much good to you in the long run.
One may not feel comfortable flying DR, perhaps that is because said person is experienced with the proper kit to fly navaids and GPS and knows how to maintain their SA, I'm not that kind of person but people like IO540 do seem to know their stuff and I'm not going to say my way is better than theirs! On the other hand if said person is inexperienced, then a GPS is probably not going to be a solution their problem.
