I just bought a new lakland Hollowbody-30 and the strings on there are great!! I want to replace them with A pressure wound or brite flat. Here's the question. Whats on there now are 45-105 . Ghs unfortunately only makes Pressure Wounds ( My all time favorite string) In 40-96 GHS makes a Brite flat in 49-108 . What would be closer to what i have? I don't want to mess with the truss rod if I don't have to. or any other suggestions?
