The BowTechs are rated with the Hush kit on. The 2003 speed chart says that with your 28 inch draw, IBO speed for the BlackHawk would be 291 to 299. The wife' s LadyHawk' s grip is very comfortable and feels very soft. You will like the adjustable draw stop pin on the Infinity cam which is very durable. You can adjust your draw length and letoff with this stop pin, something you can' t do with the FX.
