I use twisted wire hangars also. (Most of the time) With twisted wire hangars there is probably 3 or more times more contact for the epoxy and wood. Most of the time I also either drill my hangar or line tie holes all the way through. If it is too far, say with a tail hook, then I drill the hole deep enough for the hangar, then I drill a vent hole in from the top of the bait. Holding the bait, tail up, I start 30 min epoxy in the hangar hole, then I warm the epoxy with my heat gun and keep adding epoxy until it comes out the vent hole. It doesn't take too long because there is no air lock like there is with a dead end hole.
