What endpole system are you using? I have my own endpole that works great! Maybe you need to tie a knot to keep the dousing points about 8 inches from each other when they are entering the snuffer.
Are you trying to douse to early? It is actually easier to douse while rounding into the wind, especially with the endpole system.
Holmenkol on the sail works well also.
