berlinwood is a great choice! They are my go to board! the difference in 29mm and 32mm is very different. 29mm is skinny where 32mm is wide. Depending on how big your hands are, i would go with the 32mm unless you are very young and have small hands. 32mm are overall easier to use and easier to learn with. Keep in mind though, 32mm decks mean 32mm trucks so that means blackriver trucks, ytrucks, or tech deck longboard trucks (off amazon). Although you can use 29mm trucks on 32mm, it just isn't that convenient.
