Done quite a lot in the sim, but only as the victim. Been on the receiving end of SASless's ADI trick, and he's right about spotting the real instrument fliers.
(SAS your not bald and ugly with very short legs are you? If you are I've recognised you.)
LOFT training was excellent value, and the chance to spend some time looking at snags which had occured over the last 6 months in slow time was perhaps beyond price. We always used our last session as a chance to go through problems which had occured recently, sometimes reading about a problem doesn't help understanding, seeing what happens to the AC does.
Personally I couldn't reccomend sim time highly enough.
