"Heres an interesting one for discussion, given that, for achieving an FATPL taking an integrated course is by far the best option"
..... is it ?? How does that work then ? I can think of many good reasons why a modular route can be better.
Anyhow, I suspect FFF has the real reason. When you have a choice of either shelling out £40,000 or £70,000 for essentially the same thing I think most people would choose the cheaper option.
