I believe Bill Roberts recently mentioned that the best place for the spin. hound was one third of the way up from the main hounds. Measure the distance from the main hounds to the top of the mast, divide into thirds, one third up. The topic he was commenting on was mast survival. The Tornados I've seen have the tang half way. My Mystere is half way. I don't have any experience with Hooters but it's my understanding they produce greater loads than a spin. I would opt. for a lower tang and get the sail recut. Less hassle than replacing a mast.
