Quality work 👏👏👏.
With regard to string trees, unless you’re going for a slavish recreation of Leo’s original design, those 3 string affairs are the way to go.
I bought an Alvarez hybrid 15 months ago. Really good value for money, plays nicely and sounds good (even better with a new set of Augustine Reds). Needed a little fret end attention, but very pleased with my purchase.
