Charles-
<br>Do you have the ORIGINAL 5.7/5.0 rudders? NACRA upgraded the rudders in late 80's or early 90's and made them larger- should help. Also, as an old 5.0 sailor I would agree with the comment to have your crew weight BACK- getting the bows more or less out of the water and the rudders IN the water. My 5.0 used to get kind of "squirrelly" in heavy air downwind due to the great effect on center of lateral resistance (CR) when the boat heals (as in a puff) when the CR would suddenly move from it's "normal" position forward as the bow dug in and the rudder and skeg came out of the water! Once I knew it was coming and tended to do that I just dealt with it. But to do the "Wild Thing" effectively you have to be able to control the boat well since you are basically "balancing" it, similar to flying a hull upwind and unless you can turn quickly and with (relatively) little drag IMO it won't pay off playing the rudders. I would never try it on my old P 18 with stock rudders since they cavitate at speed downwind going mild!
<br>What you MIGHT try would be to get the hull flying and play the MAINSAIL rather than the rudders (or have you crew do so) having the crew ease the traveler in and out slightly to balance the boat while you keep the rudders more or less straight.
<br>I KNOW this isn't "How you are supposed to do it.", but those "rules" were written by sailors on board boats!
<br>Let me know if/how it works!
