Blood wizard, Maxallure, skate mental are all 14 wb
@ 8.25.
If you want bbs wood business & company and doom sayers do a lot of 14" wb.
Tumyeto occasionally does them as well, last one that caught my eye was the Dakota Servold that came out around the time his Emerica part dropped but I'm sure there's been others.
SoCal, the warehouse sites, and spot will let you search by WB.
Not sure what happened with your FA because the last thing I'd call any of the ones I've had or looked at in person is flat. Did you get it from an actual shop? I've heard that there's counterfeit ones out there to take advantage of the hypebeast types that buy them to put on the wall.
This has happened to me a few times. I eventually found out that it was the length of the deck that was messing me up. Might want to check that out.
Length is something I've noticed a lot of people don't really pay attention to, but it (and it's relation to wheelbase) are just as important as width, wheelbase and concave in my opinion. Some tricks are significantly easier on a short deck.
