I did that years ago but without video cameras (no mobile cameras back then). There were no "decent WC/WT guys" and they were quite high ranking. Did try out a lot of martial arts in friendly sparring from boxing to Tai Chi. Most dont want it recorded and I respect that as they earn money with their reputation. MT is still on my to do list (Lethwei too but I am too chicken to ever try that out) . Thats what martial arts is about in my book. I come from a japanese ma background so your "western inferiority complex" theory is strange to put it mildly.
I agree at some point its about put up or shut up, thats why I asked you to upload a video of yourself. Not sparring necessary but demonstrating your strange theories (Remember your lead hand forward thread?) . But nothing ever came of that did it. And why dont you just post a sparring clip of yourself as you obviously are a longtime practitioner and deem WC as effective? If you are too old take a clip from training partners, students anybody.
Discussion without practical reflection is useless at some point in martial arts and we have reached that point a long time ago with you. Its nice that Sergio crosstrains but its about the nonsensical approach to fighting with WC and the stupid stuff he said in the video. Its about WC itself. I know that BJJ is highly effective. Link me a video of him sparring with WC. And I mean sparring not just playing around with his students.
I have asked for years for legit sparring videos of WC guys and never got one. I know of MMA fight teams out of WT schools in Italy but then I watch them fight and they just use the crosstrained ma like bjj, wrestling boxing and no WC at all. Give me some adresses in europe (mainland) to in your estimation legit guys. Once Covid is over I will try to visit one of them if its not too far and I am back in decent shape. Or I will just visit the local WC gyms. There are several. If they allow I will record and post it. If the adresses are farther away (US..etc) I am sure we will have other members able and interested to look it up. Or you invite me or other members living near you to your gym for a friendly sparring. Were are you located?
I never trained in WC . I tried it out and sparred with them. The Dempsey book is and will always remain one of my favourite books ever about martial arts. An inspiration.
We are discussing the technical details of force development and the answers are not obvious even just from the few studies on Western boxing since the body is a dynamic system and there will also be variation based on type of punch thrown, angles etc.
If we want to examine another system where punching force is generated with a different but overlapping concept especially emphasis of tendon power then that will take further time and there are even fewer studies.
This thread therefore started with the observation that Wilder, who has skinny legs but a large upper body and core and clearly powerful fast twitch muscles and tendon strength can generate huge KO power without apparent much use of legspring although he does use it at times in straight punches, and hardly in his swings (I won't call them hooks).
I have liked and used the Dempsey book for years and it is popular in the WC community due to his emphasis on shoulder whirl, the bottom 3 knuckle landing punch and the falling step all of which have an overlap with WC theory.
I'm not interested in turning this into a discussion about WC or my specific training and derailing thread.
The question immediately comes "why haven't we seen WC in mma" - different thread, threre is already a thousand post thread on that elsewhere.
The the next question "does WC have power?" A style famous for close range power but you have to feel it yourself.
Posting a vid of myself would serve no purpose and not settle any arguments.
You call strong hand lead stance 'strange' but it is not uncommon in mma and favours bridging striking and grappling better.
I have felt the power of high level WC punches and had the bruise's to show for it, as well as delivering the same to others
For legit WC schools although I can't vouch for the quality of each instuctor I would say Wong Shun Leung lineage. So schools under these association are under WSL direct students.

I think you said you were in Germany so if you are really interested these guys are in a legit lineage although like I said I can't comment on individuals but if they have experience and have been certfied to teach they should be good at least.

Mostly these schools cater for hobbyists and WC anyway isn't trained usually as a combat sport, but some of the instructors teach professionally and a fair few have done challenge fights and/or cross trained or competed in some form of combat sport.
So again, if you come in with a respectful attitude and ask for a friendly spar there should be no issue at most of these places. Probably if you ask to do it separately after the class or you want to go heavier is best since there no point doing it front of regular students. If you came in with attitude, you would likely get hurt. So its about respect but otherwise yes they would probably be glad to have someone who is interested to learn and find out if it is 'legit'.
