Archbishop, I too have just passed and I reckon of course experience is an important factor however so is currency, having taken 11 months to do my PPL I've done 105 landings and 46 hours in the last 12 months and of course been supervised by a 9000 hour instructor on many of those.
To be honest Ive been shocked to see some very experienced old hands do some terrible landings after a winter without flying, some embarrassing. I realise that you dont go if you dont feel competant as a new pilot, safety first.
Maybe its a lot of these old know it alls knocking you!
