I dont think there is a difference, but vsbabolat will know. I decided to have 6 grams of silicone put into the handle. That way I can keep the balance close to the same, which is how I like it, and have the Hydrosorb on both sticks for consistency. I love the prestiges right at 11.9 after og and damp. I feel like they are perfect that way. I wish I could mod the Youtek retail to that weight as well.
