Titleist has always been known for their classic designs, so this shift is definitely a departure. However, I've found that sometimes these changes grow on you over time. Remember when TaylorMade introduced the white drivers? Many were skeptical at first, but they became quite popular.
That said, performance is key. If it outperforms the TSR3, you might find yourself warming up to the looks. It'll be interesting to see how it performs in real-world testing.
