That is great, the saddle on my Favilla soprano is part of the bridge and is not removable. I bet the harder wood saddle will make it sing even more.
I like Martin strings on my vintage mahogany sopranos, Aquilas tend to be too punchy and harsh on them for my tastes. Also, seems like the Aquila strings have more tension which I don't mind not having on a vintage ukulele. Enjoy the heck out of it!
