I’d go longboard all the way, forget minimals, in my opinion they are a frustrating compromise between long and shortboard.
When I was starting out I took the predictable route of going for shorter and shorter boards, easier to get out back on using duckdiving, greater manouverability. But unless uber fit, it’s very tough to get into waves early enough, unless you are surfing multiple times a week! Ea;ry on, smaller boards mean fewer waves and less fun!
Using channels between breaks you can still get outback on a big board, unless it’s properly firing, but then it is possible. And on a small day a londboard will be a lot of fun. Leanring to turn a big board will teach you loads for when you do try a smaller board!
