let's provide correct info
Paratrooper has come here looking for info, so let's at least try to be correct. Took a minute to look up the relevant info in LASORS.
Flying training: a holder of an ICAO license who has flown a minimum of 100 hours PIC only needs to pass the skills test.
Theoretical exams: same 100 hours, then you only have to do Air Law, Human Factors and the RT license.
Reference for above LASORS C1.2 and C1.3
So, I'd say - again - go for the FAA PPL, fly your 100 hours and then do the above. Voila! You've got both JAR and FAA.
There's actually another advantage to having the FAA license also. If you intend to fly in countries that require a validation of your license (SA, OZ, etc), then it's a lot quicker, easier and cheaper to validate the FAA one. This from own experience.
