Can't give advice with the benefit of hindsight. At the moment I am planning to complete my flight training at Tayflite after the ATPL exams (all things being well!). However I do know more than a couple of guys who have experience of Tayflite and more particularly of Syd Utting who does the CPL and FI course up at Perth. Generally good feedback on tayflite but nothing but the highest of praise for Syd both professionally and personally. Have a search for "Utting", there are a couple of CPL threads linked to him.
For your info there is a CAA Examiner on-site and I believe another who lives locally. So no issues in regards to test.
Regards and good luck wherever you go!
Paul.
