It might surprise you that I avoid Fairoaks for the same reason.
My point is that their weight-based fee schedule is OK for fixed-wing (for which it was designed) but to apply the same weight-based schedule to helicopters is a rip-off. I feel you rip-a-me-off, I don't come.
Not trying to convince anyone, I fly my way and you fly yours; everybody happy.
