If you don't want your heart broken, do not put on a leader, imho. At least not for this application. By having a leader, I consider the knot, although it may tied on perfectly, a weak spot. With such a powerful hookset, if there is going to be a failure, the leader knot will be one location. Second would be the tie off to the frog. I "always"!! Tie the frog straight to braid.
