I bought these for my Taylor 310ce, they are the same strings Taylor shipped stock on that guitar. They are quite thick and have a lot of tension to them, I struggle to to perform a full step bend with these on the 2nd fret on the G string, but they produce a strong and thick tone with strummed open chords. The tension they provide ensures the guitar always stays in tune, even when played aggressively. I tried a few other string manufacturers & gauges on this particular guitar, but I encountered intonation problems with those and eventually I reverted to using Elixir strings once again. These strings last quite a long time and don't corrode easily. There is a reason Taylor ship Elixir strings as standard on their guitars! Highly recommended, especially for dreadnought steel string acoustics.
