1) The A spin (more affectionately referred to as the butt spin) it's hideous and unfortunately it's gaining popularity. I don't care how 'great the butt looks', there is not aesthetically pleasing about your butt being the highest body part.
2) Not sure what the name is - but it's a sit spin where the skater is completely compact at the ground, like a ball - it's like the opposite of the hyper-flexible spins, it's a spin for non-flexible people.
3) moves where the raised foot is bent back - I've seen Evgenia do it for spiral sequence and spins - it's unattractive
