So i got a new driver?

Okiee so i got the TaylorMade Superfast 2.0 driver. It's white, has a loft of 10.5, has a low torque shaft, and a ladies grip. Btw i'm 13 years old. Its definitely different from my old TaylorMade SVG with a loft of 12. Now my new driver, i tried it out, its lighter, and makes a DING! noise when i hit it. I feel i did better with my older one. But what can i do? Oh and i feel like i messed up the grooves of it. The white inside the groove smeared and won't come off. How can i feel better with my new driver? My coach mentioned it would give an additional distance of 20 yds. I haven't gotten that YET. XP
