Now that's a pizza cutter.
Hulk and Wanda. There must be a story behind the names. How long have you had them? Can you still tell a difference in flavor between them?
Normally over time a sourdough starter changes to the local yeast varieties, so Hulk and Wanda should be converging in flavor. Fifteen years ago I got some starter from my brother in Tennessee, and I use it to make sourdough wheat/rye bread. At first my bread tasted like his, but over the years it has changed to California sourdough, and now my bread tastes very different from my brother's, it is much stronger with a bit of a sourdough twang to it.
