Other fringe benefits:
1. No worries about taking an IR within 18 months of the ATPL writtens.
2. You can hold down a well paid job during the week and earn more than an FI while building your hours up.
3. You will have more hours when you go for your CPL
The only snag I can see is that you will have stricter weather minima to work to than the CPL people.
