Once again, thanking you all for your input and answers!!!!
I know this may sound like it is ground that we may have covered, was at work the other day and noticed that the B777 wing tip had it looked like to possibly be the birth or what we now called a raked wing tip,( it's not that prominant) any idea's and input from the 777 drivers.
Back to super critical and critical wing shape/form again. Heard that the difference between the two is that the one has a greater leading edge radius that the other. one was a improvement on the other. any ideas/answers.
