V1Rotate,
The only problem I've encountered is that the 3 Arrow's used for CPL training are very busy and people taking 170A's or skills test take priority (as one would expect) which can lead to the odd flight here and there being cancelled when the examiners are in. But then I guess it is not so different from a bad weather canx if you look at it that way - frustrating as it is, but everyone gets the right amount of hours in eventually.
Everything else has been ok so far.
