I copied so this is not an original...but instead of the becket, I tied a small line to a stainless steel hook from the eye-strap that the primary ratchet block connected to. Two blocks are attached to the spin clew. Each sheet goes through one of the blocks on the clew of the spinnaker but they each end in a plastic bozo ball with a stopper knot which keeps them from pulling through the blocks. Normal sailing? don't change anything and you have 1:1 with the balls bottomed out on the blocks on the clew. If it get tight and becomes worth the time needed to connect the 2:1, you go to the low side, grab the bozo-ball at the block on the active sheet at the clew of the spinnaker and drop it in the hook next to the ratchet block on the deck....instant 2:1. Our spin sheet was just long enough that you can still snuff completely with the 2:1 connected but you would have to disconnect it to gybe and reconnect on the other side.
