a back to blind you dont pass the handle in the air, and a KGB you don't land blind, anything in the middle is either a back to front :)(if you dont pass the bar for a KGB), you may also call this a back to back or back to heel with an allehoop,; or a back to toe with an air pass ( because now your not technically landing blind any more hence it's not a back to blind with an airpass cause you cant be blind if your lead hand has the bar???), with a back to back or back to front ( whatever you want to call it) actually being a kgb (if it's passed in the air) , or have i got it all back to front ?
