I would advise going the 666 route.
I have never surfed, got a 666 at age 51 I think.
First flatwater, then tried surf.
Four years down the track, with admittedly not enough time dedicated to learning to surf, I can sort of surf the 666.
I can ride a wave at the beach, usually ending badly.
But I can attempt well away from any "real" surfers, generally in reformed waves close to shore, very unthreatening.
Having had some success on the 666, I thought I should try a longboard.
Zuesman advertised one that took my fancy, gave me an excuse to do a roadtrip to Sydney to collect it.
Travelled back via the South Coast, Gerroa, Batemans Bay, Merimbula.
Finally decided to try it at Pambula River mouth.
11' Munoz Glide, possibly the biggest floatiest board you could find.



I got it off the Kombi, unwrapped it, and carried it down...

After tail standing the thing, I sort of figured out where to lie.
Sort of.
I was probably 94 kg, and the thing wanted to sink at one end or the other.
Impossible to paddle.
Managed to get moving.

Knee paddle

Just,
but it ended badly.
No way am I approaching surf on this thing.
So get a 666.
Surfboards Impossibly hard, before you go anywhere.
Unless you have residual muscle memory from your youth, forget it.
But I have bought a "Deep" prone paddleboard, to learn paddling lying down.
and it's going to take a long time.
But I will get this thing in the surf one day.
There you go Crispy, I reposted it.
Can't believe how you blokes paddle out, much less turn and catch a wave.
Pop up? Forget it!
