Great question. One thing to check is that your hips are staying above your shoulders while you wrap the foot, if you sit up too far in the front balance, it might tip into a place where holding the press through the hand becomes too hard.
Another option is to key over into your front balance with the legs tucked to wrap the foot before you start sliding. You can also play with building endurance in the front balance fold by seeing how long you can hold it and how far you can adjust the shape of the body and still maintain control. Let us know how it goes! Happy training!
