OK- I said earlier in this post that all my Taylors like D'Addario EXP16s. I recently experimented on two guitars using Elixir 80/20s and D'Addario coated 80/20s, and I'm back to the EXP16s on both guitars. The EXP16s perform consistently well across all my guitars, enhancing volume while providing fullness and richness in the tone. Both newer guitars have less of the Taylor signature sparkle with these strings, but I think that it has more to do with both of them having CV bracing. 80/20s just make the guitars sound a bit thinner and sort of wimpy, so I'm sticking with the EXP16s for now....it's nice to have the variety of tonewoods and bracing among these GAs - each one has its own unique, but pleasing voice. Anyway, I digress...
