PPL............ no question. If you do the minimum NPPL syllabus it means doing a 100 nm xc, but the ppl is 150nm,so why do the 100?.........I did and it was a mistake, as I now fly almost always with a friend and can't be ar$ed to fly a 150nm solo xc to qualify the PPL. The minimum 32 hours soon expands to 35 then 40 then 50 therefore the minimum hours for a PPL are soon achieved.
In my defence I hold a Glider Pilots License which meant that I could do the NPPL in a vastly reduced minimum compared to the PPL.
If there is no medical reason to hold you back and money isn't too limited........go PPL
