Sounds like a small move towards friction, or playing more direct at first would help. This is especially true if you're "mostly up the back of the ball".
EVERY BALL needs to find adequate friction before it can change direction. Merely trying a different ball would not likely be the cure all because the ball will still travel in the direction of it's rotation (after it finds friction).
Why not experiment with adding more rotation to your release, so when the condition allows you'll have a plan B? You'll still have your natural release as your A game. Just a thought...
