i'm under the ITKF banner, which means nothing to people outside the shotokan world, but it has many differences from the origional JKA style, and the modern KUGB style.
what i consider to the be older JKA style:http://ca.youtube.com/watch?v=rYG4OpE9lR4
this is what i consider near the pinicle of technical skill in technique for these guys. not my cup of tea, all shotokan guys have roots that mix in the not to distant past, but i'm glade what i do has changed from this stuff.
this is more of what i call JKA stuff:http://ca.youtube.com/watch?v=P0TNTFj3EuQ
this i don't like. repetetion is key for skill building, but what you repeat is vital!, lol. ippon kumite, kihon, and (solo) kata practice define this stuff. i don't like it. the only punch practiced is the full extention reverse punch, no thought to close punching. back leg kept "straight" means the hip is pulled on and the lumbar spine in placed under extreme presure on contact. but do it this way because sensei says. i don't like it.
the ITKF stuf fi've posted on here usually gets ripped by non ITKF guys, and most people in general.
this is kata the ITKF shoots for in competetion standards:http://ca.youtube.com/watch?v=gPP8s_KXEpU
these are some drills to develop timing:http://ca.youtube.com/watch?v=FBIlzeeFQ2ghttp://ca.youtube.com/watch?v=fUYqrcU0RW8http://ca.youtube.com/watch?v=2JeuvI5bYFY
alot of people don't like the ITKF, i do. i think it's got it's flaws too, plenty of them, too many to list here, lol. but they apply to shotokan in general, mostly.
what it's got to offer that the others don't is, in my mind, a reason behind everything in shotokan that makes you think "ummmm, why am i doing this?" real scientific/commen sense reasons why we do things the way we do. which i can sink my teeth into alot more then having some one tell me to do a kata 1000 times before next week to improve my technique. which is nonsense.
