"So is there a teacher that does the push-hands for Peng Ji Lu An, etc., and has applications such as Chin Na, Dian Xue, etc., teaches classical weapons, etc., without requiring like 20 years of study so that by the time you're done you're an old man?"
No. T'ai Chi takes that long to learn, no ifs, ands or buts. Sun Lu-t'ang became high level in T'ai Chi Ch'uan after about 5 years, but he had spent the previous 20 learning Hsing-i Ch'uan and Pa Kua Chang. It takes that long to recondition the body to be able to do p'eng, lu, chi, etc. correctly every time. If Erle Montague wants to leave that out, as you say, that is his prerogative (many others do, too) but he is not teaching the traditional art of T'ai Chi if that is the case. I'm not familiar with his programme, so I can't make a definitive statement about him, I'm just going by what you are saying here. I have been told by high level teachers that Dim Mak is not a part of T'ai Chi. We learn to defend against it, and we learn how to use points for offense, defence and healing ourselves and others, but I am told it is considered barbaric to just study how to kill with them as the name Dim Mak implies, apparently.
There are the Yang family and the Wu family who still teach the traditional way. I assume (or hope!) the Ch'en family does, but I cannot say for sure.
Yang Jun, like my Sifu, Eddie Wu Kwong-yu, is a lineage holder, a direct representative of his family's art, so it makes sense that he would be more likely to demonstrate some martial. Sifu Eddie traditionally has had to show students and challengers a thing or two at the right time. Once, he had about 10 of us push on him, hard, from all different directions and seemingly all he did was breathe out and he sent us all flying. I've seen him several times break furniture to demonstrate to people who claimed T'ai Chi had no "power," I've seen him put a spear through a cinder block wall inches from a sarcastic student's head (a student who should've known better), I've seen him lock challengers up until they submit, once to the point of he had to break the leg of a macho Judo guy who came in swaggering about how T'ai Chi was for "old people," and tried to throw him by surprise. The guy ended up becoming a student. I have heard stories from my seniors of how he and his relatives have defended themselves with results very much like the old stories. Apparently the Mong Kok (Kowloon) Police were so impressed with Sifu's late father Wu Ta-kuei (when they were investigating a bar fight in which he subdued 20 armed attackers) that they subsequently hired him to teach restraining moves to their officers, which he did for 15 years. I don't know if you've ever had any dealings with the Hong Kong Police, but they are pretty tough guys already!
As Jerry K. says, high level guys can break bones without too much effort, and depending on what comes in at them sometimes they can't avoid it, as in "instant karma." When you are in the presence of such a teacher (and you have the native talent yourself to learn from them) you will know. The point is, you have to go out and find your teacher, the onus is on you. If it is your fate, you will find a good one. If not, do the best you can anyway and maybe in your next life you will earn one. I'm not being sarcastic, that is the exact language some traditional teachers use.
