From personal experience i would go for ATPL(H) with Bristol G.S. I know some friends of mine didnt get through CPL exams and they were not the only ones. Not blaming Dragon (the school they used) but the exams for CPl are new...i.e the database is new. At least it was 1-2 years ago when they started. Not great feedback so the school cannot help you much.
Bear in mind that Dragon has copied B.G.S bookes anyway(with threir permision) and just removed some bits from them and named them CPL....
Go safe, go with BGS, prefesional people and they will get you through. hammer the database and you'll be fine. You never know, you might change your mind in less than tree years about IR...if not you will just have a normal CPL after 3y...
Good luck
