I see no one answered your question. Did you get the rosin?
My thoughts are that if you need a sticky feeling to your fingers that perhaps you are relying too much on hooking the string rather than a glancing kind of pull, which actually will get the string to jump faster than trying to hook under it.
Now if your fingers are too dry that's another issue. I use a cake of bees wax lotion bar. Something like THIS
This does two things - keeps my hands moisturized and a wee bit sticky unless you use too much, and it also helps reduce friction which helps to prevent the skin from chaffing too much.
If you use too much your fingers can become a bit slippery, which you don't want. Keep a cake of this on your speaker cab and every few songs rub the cake with your fingers.
But mostly, experiment/practice with using as little hook as possible by glancing the fingers off the string at an angle. You can work up better speed this way. Instead of using your whole arm/elbow, use mostly the wrist in a circular motion and flick the string off your fingers at a glancing angle. Once you get used to it, the strings will kind of jump and snap back, and it will be like dribbling a basketball. Try to work at NOT having to hook UNDER the string to get your snap.
When you hook and use the whole arm you are pushing and pulling string up and down and it's harder to get the string to rebound naturally and work for you.
