I think as
@Xen said, there are a few boards listed as the 8.3 through 8.375 to 8.38 that are often quite different, depending on who makes them or which brand or batch they come from.
I am more familiar with BBS wood, given it is more mellow and I can usually get good shapes that work for me, as well as almost no shortage of the same boards over and over when I want them.
That DLX twin 8.3 is a fav for quite a few people, definitely wider than 8.25 but less than the DLX 8.4 or even the DLX 8.38 (which is so close to 8.5) from that range.
Other non DLX brands with approximately the same 8.38 x 32.2 with 14.5 wb boards can use the same shape for their 8.38 (including Element, DGK, Birdhouse, Baker, Heroin, Deathwish) but there is a more generic 8.3 shape from BBS that is more like 8.3 x 31.95 with 14.375 wb that is used by most of the more mid range brands on BBS / Generator from what I have seen too.
I have boards from local shops on Generator 8.38s that are the same slightly smaller size, which I believe are the same as the Passport decks, along with other brands including Alltimers, Carpet and half the other BBS listed brands.
All these boards are definitely not blunt or squared off, with more pointed kicks than others, if that is more what you are after too.
I have come to really like the DLX / bigger 8.38 with the 14.5 wb as my main ride, on Indy 149s, but others ride it on Indy 144s / Venture 5.6 / Thunder 148s and it works well for them too.
That size and shape gives me a bit more room than the average 8.25 but is a little more nimble than the average 8.5, so a good in between board that I can use for everything.
