OK, I have to make one comment on this. An unloaded snap is not a "cheated" snap. Properly done snaps in full scale are also unloaded, or even excellerated with opposit elevator, in order to retain as much energy as possible.
Even with models, loosing the line through a snap is a result to a great extent of loss of energy through the snap. For a snap to be a snap, the model must be stalled. Unloading elevator after the pitch break does not mean the wing unstalls. In fact if it did stall through the pitch breaK and yaw departure it will stay stalled through the snap even with elevator unlaoded.

I just hate to see anyone limit his flying by taking the "safe" way out and burring snaps. While it'll never be a zero, on difficult snaps such as up or dow lines it also never be a high score either.

I,ml writing an article on snap technique. Doing a well exectued, unoaded snap isnt nearly as hard as you might think. Its a change in technique, and of course a proper set-up of the model. But like anything once you learn it ,its easy. Easier actually for the overall snap than just cornering the sticks IMHO.
