This is the first time I used the EXL125-3D with 009-046. I usually played 009-042, also from D'addario, but decided to go a bit thicker. I wasn't disappointed. Their strings continue to be the best on the market for the price. Sure, there are better strings out there, some that last longer, but the EXL125-3D comes with a great combination of quality, durability, and affordability.
