What is your highest jump achieved 50% or more?
If you are doing doubles, and you like Jacksons, try the Jackson elite plus, your blade should be coronation comet.
WIFAs are very narrow. Hence the problems you may be having. Check out the Riedell Silver Stars, in that case or the GRAF Richmond special.
Graf's are a fairly light boot. If you are looking for light, you may want to go to the brand new Riedell 1350LS. I have not tried them yet, but am considering them for my own child. She is working on her double sal, and loop.
Once you are over 100lbs you may need to move up a class - say the edmonton specials v the richmonds especially if you are pounding those doubles and working on triples.
Stick with Wilson or MK blades. The comet will give you better edge control at your level and better longer glides, while the ace will make you work a bit harder to achieve a longer glide. both are great though. Ask your coach what kind of toe pick they want you in. Cross cut? then get the Ace.
Good luck with your skating.
