That's what an older Australian guy who ripped was telling me to do many moons ago.I think adult learners can benefit from occasionally surfing a longer board. It’ll help learning to use the rails with purpose. And will definitely smooth out choppy style. Those really short wide tail boards seems like the drive is done off the fins and not engaging the rail enough. Just learning floaters and carve downs on a 6’4 or longer helps with fundamentals.
He made me and my friend ride a mid length all day and focus on having purposeful movements. He said we were too twitchy and indecisive. Commit and have confidence in your rail. Helped smooth me out a ton. I might need to do that again actually.
