I take it your looking to stay north Obs Cop. For the record my experiences at the moment are with Professional Air Training (PAT) at Bournemouth. As mentioned earlier finding a good school and good instrctor in one place is quite rare, but here you have both!
One instructor does the part time training (from my understanding), they are busy at the moment, but certainly worth making contact with.
As for the schools you have mentioned I can not make judgement having not had dealings with either.
