Video tape yourself, it really is nice to see and show others to help pinpoint what is going right/wrong.
I'm in same boat. I thought I would be throwing 3's by this time of the year, haahahaaa not so. I'm still trying to nail straight airs consistently.
Start small, get them solid and keep adding from their. Grabs, shifties, then slowly move to a little bigger jump and start again getting everything down solid.
Keep us posted and post a video.
