If you’re still learning double jumps, e.g. you land 2T, 2S but still struggling with all others, the Chorus model is still for you.
If you already have all solid double jumps, learning 2A, you can upgrade to Ice Fly. Do not be fooled by its comfort, the padding hides a support structure suitable only for that level.
NOTE: This is a general guideline and other factors such as weight, height and skating style should be considered. Always ask your coach before changing models!
