Hi,
I completed my MEP & initial IR at BFC on the Seneca & used the same aircraft for both the IR & MEP. It was a very useful start prior to the IR training gaining 6 hours on type. They are also 200T models so it is useful to carry out IR in the same model.
As you are converting from FAA you will want to complete in min hours so if you practice out of Bristol during the MEP & familarise yourself with the aircraft/avionics it may save you vital £s during the IR.
Dont forget if you save £350 on the course of your MEP by going elsewhere it may be used up having additional hours training on your IR aircraft section!
Best of luck
