I think you will simply because you're increasing the balance AND forgiveness. To increase both of those and keep the same scales and meter is a bonus for you. Balance will help keep putts from wandering off line and you will notice they seem to roll smoother.
One thing-don't expect miracle putts. You still have to get the feel for it and that only happens after you've putted with it for a long while. I don't think your learning curve will be very big with it and wouldn't be surprised if you adapted to it right away. GL
