I recall I posted this thread long ago but I forget the correct answer to my question. According to one website I came across:
3a/3l, 3a/3t, 3z/3l, 3z/3t......... in that order, with the first jump as the determining factor.
I thought that should be it but it just wouldn't make sense. How can the 3f/3t combo be more difficult than the 3l/3l combo? Just how much more difficult is a 3f than a 3l that even a 3l/3l can't match a 3f/3t which has the much easier toe-loop jump? Something is just not right. What exactly is the correct order of the difficulty of 3/3s according to textbook not to an individual skater per se? Can someone enlighten me or give me the links? thanks in advance.
