One trick that helped me was to stomp on the switch and then throw as hard as I could, horizontally, before too much tension built up. This gets you some airspeed before you get lots of line tension trying to pull the nose up. You might try throwing the model without a winch until you can throw level and far. It's important here to start with your arm extended back, although this can feel strange at first. Otherwise you have much less distance available for your arm to accelerate the plane. I don't know how many people I've seen just lightly toss the model in a manner guaranteeing a stall and crash if the winch line wasn't pulling. This technique does require careful timing and probably reduces height just a bit, but it helped on an 85oz plane with 134" span and a deep fuselage. Another suggestion is that if you have a deep fuselage (i.e. Mantis) you may need to have the hook forward more than for a shallow fuselage.
If you don't have elevator compensation for the flaps, you won't be able to use much, if any flap on launch. You might also want to carefully check your towhook to be sure it is not mounted with a slant, and to be sure it doesn't bend when you pull on it.
