re: Golf board: 10.5 vs 9.5 loft?

Really depends on preference.

When I was younger and learning, I struggled off the tee. I moved to a 10.5 from a 9.5 and absolutely loved it. It's "closer" to a 3 wood and easier to hit, I find.

I now hit 9.5 lofted driver moved to 8.8 (C2 on 910 D3 Titleist Driver) and it flights well for me while still keeping control with it.

The distance changes on the environment as well, soft fairways or wet conditions you could most likely hit it farther with 10.5 with the longer/higher carry. Harder, dryer conditions, a degree of loft could at 10-20 yards with rollout/release, which in theory could equal a club or 2.

There's no definitive answer imo, golf is a game of preference and individual swings, but depending on you handicap, 10.5 would be a lot easier to hit, but TYPICALLY wont go as far in regular conditions.
