Swing out and get up into a Meat Hook position at the frontend. Hold the position at the backend. At the frontend, open out as for a Whip (by keeping the legs in position and opening the upper body) to make the catch.
The lines are difficult for this trick because without any special preparation, they will wrap around you as you get into the position. You can use a Twisting Belt, although in this case the bulky belt can make it difficult to hold the Meat Hook position. Therefore the best is to add a Full Turn to the lines before leaving the platform.
