I used the Sporty's DVD's myself some years ago when I did the FAA IR. The DVD's are very detailed and well worth having. There was plenty of practical advice in there and I can't see that it would do anything other than good to watch them. I seem to remember they were not cheap, about £150ish but I flogged them on ebay and got most of that money back. They saved me a few hours of training and paid for themselves and then some. Don't skimp on training materials; if you can afford the King stuff as well then it would be a good buy, just flog it on ebay later on and the cost will be very low. Hope this helps.
