Sourdough changes greatly in it's first 25 years. In Alaska sourdough starter over 50 yrs. old is coveted, and some are over 100 yrs. The differences after 50 yrs. are more subtle, but a new starter compared to a 25 or 50 y.o. starter is no comparison. You will be much happier with as old a starter as you can get your hands on.
Fortunately for you, my Mom started her starter the same year I was born, so 53 yrs. now, and I will be happy to donate to your new hobby.
Alaskan sourdough is used more for cinnamon rolls, pancakes and such, but also makes fantastic bread. My favorite bread is AK. salt crusted, Rosemary, sourdough.
My Aunt uses her starter (from my Mom) to make really good muffins. But my Mom has a sourdough pancake recipe that will make you think your tastebuds turned into clitoris'. Our family has deemed it illegal to use anything but the best grade of true Maple syrup with them, so keep this in mind if you should want the recipe.
P.S. While the starters listed in those links are old, it's not the same as a starter that's been in wet form from the beginning. Trust me on this!
