Collin Morikawa will be using TaylorMade’s new Stealth Plus driver this week at the Sentry Tournament of Champions, according to a blog post at PGATour.com.

The new long club has reportedly given the two-time major winner an extra three to four miles per hour in the speed category, going from the 170-172 mph range to around 174-176 mph.

Here are eight things to know about the Morikawa’s new TaylorMade Stealth driver:

1. It marks the first time in nearly two years that Morikawa has switched drivers.
2. The Stealth Plus will replace the SIM driver he used to win both of his major titles.
3. While Morikawa’s iron play is next-level elite, his one shortcoming is a lack of length compared to his peers. (Morikawa ranked 112th in driving distance (295.2 yards) last season.)
4. TaylorMade’s Stealth line gained attention last month when Tiger Woods put it in the bag for the PNC Championship.
5. This is the first week the TaylorMade club is being used on the PGA Tour.
6. The new line uses some 60 layers of carbon in its face instead of the traditional titanium.
7. The Stealth Plus is the line’s lowest-spinning model and has a sliding weight track on the sole, allowing players to control shot shape.
8. Morikawa’s spin rate hasn’t changed: with both the SIM and Stealth it ranges between 2,200-2,400 rpm while his launch angle is still around 10 degrees.

Quotable: Collin Morikawa

Morikawa on Ball Speed: “I’ve actual seen some increases in ball speed. … This is the first time where I’ve actually seen that jump, which has been great. Any time you can get a little more ball speed, get a little more distance, it’s going to be helpful.”

Morikawa on Feel: “The feel is there, which is great… The first two things that we look at is feel and sight. The red face took me five hits. (I) don’t even think about it anymore, I think it looks so clean. The carbon, it creates a feel that normally you would feel off a titanium face.”

Morikawa on Trust: “Knowing that I can trust a driver that’s not going to go left, I can hit my left-to-right cut shot and just be able to hit that everywhere we go, it’s really crucial for me. So far what I’ve seen in this short, short time it’s already beaten what I’ve had in the past.”
