Long term, I do plan to take the PPL
Question answered!
A NPPL would get you your licence quicker and cheaper than a PPL,
Do you have any evidence to support this? My experience says it will take the same time and cost virtually the same. The standard required for either licence is the same, the only real difference is that you dont need to do Ex 19 or radio nav for a NPPL. If you do both NPPL then PPL it will definitely cost you more.
