Welcome Marty, and congratulations on your new 814ce dlx....a great choice. You will find many of us here also hold Bob, Kurt, and Andy in high regard.
Regarding strings, I think changing them back to lights might be a help, but let me suggest something else, since I'm a 100% fingerpicker (with finger picks). I use Elixir HD lights on all my GA's, to get the slightly heavier string gauges on the melody strings. Just a thought, as strings are such a personal preference. I'm sure you will get a bunch more/different suggestions from others.
Glad you joined us here, enjoy your stay.
