Question Plywood choices for shop jigs & fixtures

(I decided to trust Stick and others, work without MDF for the year, and see if the decision sticks... so this discussion is only about plywood.)

I really like baltic birch. However, I need something longer than 5 feet. What kind of plywood would you use for jigs & fixtures when you'd prefer BB but need a larger size?

To complicate it...

Intermountain Wood has 18mm BB for $40.83 in the standard 5' x 5' size.
They also have 18mm BB for $72.34 in 4' x 8' size. I always thought that BB was only 5x5 and those claiming 4x8 were selling an imposter product... but the supplier swears it's the same good stuff from the same source.
Is this real?

And even if it is real, would you pay $72.34 for 3/4"x4'x8' BB?
(If it was the same $/sf as the 5x5, it would be $52.26, and that would be more tempting.)

I'd shop around. The last time I bought a 4X8 sheet of BB, I paid $57.00. That was a year ago in Phoenix, AZ.
It sure looks and works like the 5X5 stuff.

due to the fact that America does 4x8 routinely BB manufactures answered the need...
special order and an insane amount of $$$ you can have BB in 6'x12'...
be careful not to confuse BB w/ birch ply...
watch out for counterfeit also...
if your supplier tells you differently they are not informed...
consider Apple ply as an alternative, http://appleply.com/....

Back in the late 1970's and the early 1980's, I was the owner/operator of WATERTIGHT FOUNDATIONS. We were a small company of 18- workers and worked on very high-end houses and small commercial work. Basically all of the houses were MANSIONS - 20,000 square feet and more. Builders of houses such as those do not want houses with foundation problems!
I remember a very large house that we worked-on where the contractor was having us build several retaining walls. The homeowner and the architect had come-up with a plan to use engineered wood for the floor system - to enable long spans above the huge basement. The contractor was (and still is) a very good friend of mine and he had a delivery truck come-in to deliver plywood to deck the floor system atop of the engineered wood trusses. When the truck arrived, he asked if several of my guys would pitch-in and help to carefully unload the plywood. I didn't think that was at all unusual, so I sent several of them over to help. The plywood was in pieces that measured 32 feet long x 12 feet wide. It was 1.5" thick! Prior to that or since that project, I have never seen such a thing in my life! The contractor had a brochure with him showing how the plywood was made and it's made MUCH LARGER than that - but gets ripped and crosscut to the smaller sizes!
And yes - it was extremely heavy!

Use the best- FinnForm, 14ply, the best plywood in the world :https://www.alibaba.com/showroom/fin-form-plywood.html

Russian Birch is good for jigs too, Not quite as good as BB but close.

I like MDO/HDO plywood too,you can get it Melamine one side or both sides.

Herb, I'm not sure whether you're joking or serious. Sourcing Asian products from Alibaba smells like you're joking... but if you're serious, I'd love to know more. What makes FinnForm the best?

Not Asian, made in Finnland.
Finn Form is made for concrete forming but it has a phenolic coated faces that are a deep red mahogany color that are like glass, it is probably the most beautiful plywood from the mill you will ever experience. Kind of pricey.
