We fly from Barton and would definatly say that the R/T is not simpler or less demanding than some of the larger airports. The cct is normally busy and the airmanship decisions are complicated and demandins. The advantages are that you are in open FIR almost straight away. The short fields are a challenge at first, but are fun once they are tamed !! I fly in a share in a C172 from there and find every flight fun filled and I wouldnt dream of keeping a light aircraft at a larger airport with the prices and holding times :-)
