Try switching the crossover of the braid just above the hitchclimber so you have an over, under, under pattern on your braids. I've found that helps it run straight or reverses the direction of twist. I also hold a little tension counterclockwise on the knot when releasing it. With the knot your using it should run fairly straight if you hold clockwise tension while releasing it. That's my experience anyway. It changes a bit with weight and friction differences.
