Hey Creek!
Congrats on finding the Laird.
I've had 10'6" Pearson Laird Surftech, with 3 boxes, for about 4 years.
I've run it with lots and lots of fins - mostly larger singles,
trying to hang 10.
However, I do run it as a twin sometimes.
I got a pair 5 1/8" DEPTH, 7" wide fins - its pretty lose.
I've also used those twins with a small 2.1/4" DEPTH 6" BASE keel nubster.
- did some sliding around the top of the waves.
Both of those setups made it pretty lose & fun,
but if you go too far on the nose, the tail can pull out and you can
side slip (actually pretty fun) but if you go even further forward,
kerplunk, the tail will let loose and you'll get dunked -
I'm talking a foot or so from the nose - so might not be an issue.
The smallest single I've run it with is 7.5" Fins Unlimited Swept Fin.
-- also similarly loose to the twin setup and you can go further out on the nose (pretty far)
without the tail letting go - had quite a bit of fun with this setup on small waves.
It is interesting that if you aren't going to go way up on the nose,
you can run some pretty small fins. Also, with the small fins,
I've noticed less drag - so easier to catch small mushy waves - although the waves
you've posted (on the zone) look pretty powerful.
I run a big 11" sparky (actually measures 10.75)to get the best noserides but it takes a lot more paddle power
because of the increased drag. I've also run the two big side bites with a 10" HP Swept Fin (looks like a sickle) for similar noserides and drag. Yeah - I can easily steer it from the nose with the big side bites in and the HP Fin in (which is pretty flexible).
Similary with the orginal smaller side 4" bites and the original 9.5" fin in.
Its a fun board to mess around with.

I've been looking at the new Lairds - I'm remembering,
the new 10'6 is a bit wider - I think 30" versus 29.75"
and less volume 140 liters versus 154 - something like that.
The new one also weighs less 20.5 to 23.5 pounds, depending upon construction -
- I've not weighed my old one, but it feels like 30 pounds.
But the "old" shape is pretty darn good!
