I completed my training with Westflight in May 2003 and have absolutely no reservations about recommending them. It was by far the best flying training I have received to date.
Lots of quality instruction. Other organisations that I had experienced treated briefings and debriefings as something that took place on the walk out to the aircraft and on the way back to the hangar. At Westflight, every flight commenced with a thorough briefing and thorough debrief to ensure that you understood exactly what was expected.
A word of warning though - expect to work extremely hard because the standards are set very high.
