In my neck of the woods, alt-tech boards were way more common a decade ago.
Never in my wildest dreams would I have imagined that a PU/PE manufacturer building basically retro twin fins (either TKF or 70's twins) would be state of the art and the hottest thing in town.
But here we are.
It's likely that we will go more in this direction in the next decade as board manufactures cope with demand from adult learners becoming intermediates.
This process is well underway.
Also noteworthy, how easy the top pros boards have become to ride.
If I look at the Top 10, I could ride every single one of their standard SB's.
They all have enough volume for me.
Anorexic pro boards are really a thing of the past.
