So you have mastered the fine judgement required. You do not say whether you are involved in training - or indeed what type you fly.
In my experience the slip technique is much more easily mastered than the other and is particularly suited to swept wing aircraft - although effective in all.
Not involved in any training and fly spamcans (this is the GA forum after all...
). I'm just a common or garden club pilot. I dare say the majority of posters here are in the same category as me and do not fly exotica, much as I /we would probably like to.
As I say, one of my flying buddies flies Boeings and he swears by the slip method. It works for him. Crab works for me, although I'm easily swayed if bought beer.
As Chuck says, the last bit of a crab landing is a slip landing anyway, so what's the difference? I just hold off the slip longer than you do.
