I know I've posted my opinions earlier (about 4 pages ago!), but for me it's depended alot on the horse. Sam and William, TB's, are very flighty when you bring out the end of the lead rope or the stick. I don't know if that's a TB thing, or if that's because they were abused once before. Buck, on the other hand, is so great after a few minutes of CA-type lungeing, yielding HQ's and FQ's, and a bit of what I call "free lungeing"...I turn him loose in the roundpen and I can guide him with the end of one of my split reins. I, personally, don't like to lunge him until he's worn out, just long enough to establish respect. Oh, and I bought myself a pair of Mecate reins...love 'em.
But, to each his own. I prefer to keep an open mindset and not judge a trainer just because I don't like the way he's treating a horse on TV. You have to try the methods/exercises yourself, and then you can say "that's junk" or "that works!".
