@CaonnorC, there are actually several variables to consider as you continue playing and thinking about what would be ideal for you. Obviously VSL is one, as is the width of the fretboard. Another is the distance between the strings. I find for flatpicking I want strings that are close together, with an inch or less separating the bass and melody strings. But for fingerpicking I don't mind a little more space in there so my chubby picking fingers have some room. The kind of fretwire you use is another issue. Some dulcimer players prefer jumbo wire so that you don't have to press the strings all the way to the wood of the fretboard. That allows a softer touch and faster playing. And some luthiers are starting to make radiused fretboards, mainly with the goal of increased comfort of the fretting hand. It's a lot to think about.
But for the moment, just keep doing what you're doing. Those stretches should get easier over time.
