Andy_20,
There's plenty on this forum regarding integrated versus modular; if you seach this subject I'm sure most of your questions will have been answered. The 'easiest' route will be the one that suites you the best...
If you are taking the modular route then there is no reason why you have to hour build through Cabair. You can hour build where you like, just like you could do any other part of the training elsewhere. This is the beauty of modular, you are not binded to one FTO. E.g. You could do the PPL at Cabair, Hourbuild in the USA, do the CPL at Multiflight, the ME at Oxford, the IR at Tayflite....
Hope this helps,
POL.
