Great to hear about the Timberline option!
FWIW re. sharping levers: Kathy Wingert talked me into adding them to my HG, and TBH I don't use them. I'm pretty well used to doing lots of things at once with my hands, and I just can't imagine ever using them mid-song (though I do have a couple of tunes where I retune a guitar string mid-song). Maybe it's because my Wingert is huge and I couldn't reach the levers, I don't know. But playing the HG properly is hard enough as it is and I don't think it's realistic to plan on using the levers in the middle of a performance. But YMMV and I'd love to be wrong about this
