I only use yamaha NS110 for my CG, I've tried using hard tension string on my Lumanog CG before, it was a gift from a friend, they said it would add more volume and tone to my guitar, well it was nice and it felt good, almost like playing my acoustic metal string guitar... but didn't last long, it ripped the bridge off the top. I can't remember the brand but it cost about 1000 pesos.
I think it is best to ask Mr.Armando before trying it, I believe some guitars aren't build to hold hard tension strings, and he might suggest some brand that is best suited for the guitars he made.
Say! mind if I request some recording? even if it's just the sound, I always hear about the Derecho guitar but never had tried it or hear it played before.
