My test bow runs between 68 and 70 ft/lbs of KE. I think the slick tricks should work well for you, but like any 4 blade head with a 1 1/8" cut penetration is going to be less than you would get with say a two blade head or smaller 3 and 4 blade heads. That' s not to say they won' t provide enough, bigger = less in the penetration dept. Muzzys are always a great choice, but so are the stingers. You sounded like you were more intrested in the stingers and they are outstanding in every way. I would go with a 4 blade Muzzy 100 grn, 2 or 4 blade stinger, and the Slick tricks as far as that setup goes. The slick tricks are the only fixed blade head to score a 5 in the accuracy dept. You may not notice with a well tuned bow and helical fletching, but use straight fletch and you can see a difference right away. They just shoot more like a field point than any other fixed blade head I have shot.
