If the judges are to one side of you they're probably not going to notice a small change in heading in the time it takes you to roll to 60° of bank.
You want to get the bank on as quickly as you can. You'll probably find that this is easiest if you use rudder in the same direction as the bank to counter any adverse yaw. If you use opposite rudder, you'll exacerbate the adverse yaw, reduce your rate of roll and either lose height or speed.
Depending on the position of the judges, the other thing you can try is cheating! When drawing the line before the turn, you can yaw the aircraft slightly while holding the wings level. On appling aileron, with a bit of luck you'll reach 60° of bank just as the nose comes through the entry heading.
Have fun practising!
