Don,t know much about Paddy, but have heard some poor reports, plus fact he's not BHPA registerd. There are to few good instructors, many of which kindly maximise on taking your cash & flogging you unsuitable kit. BEWARE.
I would like to recomend airways, but expensive & tuition can be poor, especialy on busy days!
Good instructors are out there, but you may have to travel !
