I did the NPPL purely because of the dispensation I had from my Glider Pilots license. Otherwise I would have done the full PPL. The time and cost savings are negligible.
If you have no medical worries then you may as well do the full JAA PPL.
I am in no rush to upgrade my license, but I made the mistake of doing the 100nm qxc instead of the 150.
In your position I would do the JAA PPL syllabus and see how things progress. You have plenty of time.
Nothing is set in stone until you YOU decide. Take advice and then ignore most of it. It's your decision.
I need another 6 hours dual too, so I might offer an instructor a free lunch in LFAT when the weather warms up. If I can find one
. I do have 100 hrs solo, but the vagaries of upgrading present their own problems
