The Hooter is awesome and is nearly as fast as a spin off the wind. They are a bit flatter and you need to sail them a bit hotter than a full shoulder spin.
It is so cool to come into the leeward mark on starboard, with all the rights in the world, do a jibe while hauling in the Hooter, and come out right next to the mark close hauled. And all within the two length zone.
Also a breeze to round the windward mark, and simply release the retriever line from the cleat and let the Hooter do the rest. Best to have the sheet preset in the cleat before you round -- the sail will go out to the preset cleating position and all you have to do is steer the boat.
Secret is having a 1:2 ratio furler system. Use small stuff, strong, non-stretch for the furler drum. From there through an eyelet on the drum aft to a non-swiveling bullet block, around the shieve and back to dead end below the furler drum.
Attached to the bullet block is a big, old comfortable retriever sheet that is easy on the hands.
Now, for every foot of retriever line you pull, 2 feet of the furler line is furled.
Works really well.
