I am not really interested in the detailed specifications, I am after
reviews from pilots who have used them (comfort, features, weight etc..)
ideally comparing the pro's and con's between the different models.

I can't compare the various models, but I can tell you that I've had my
13.4's for 10 years and almost 900 hours. Between flights they get
stuffed into my flight bag with no special treatment. I find them
comfortable and they still look almost brand new.
