I agree with Ernie....Unless your a complete MORON...and visually can't tell the differences...They are TOTALLY different, BCI CAN be distinguished by VISUAL characteristics....Just becuase a Firebelly doesn't have paperwork doesn't mean its NOT a Firebelly and your just going to have to label it a BCI...This whole Notion that all BCI are all the same is total INSANITY!!! 
Below is a pic of 4 different Localities...Hog Island, Costa Rican, Sonoran Desert, and Cay Caulker.....2 mainland and 2 Island...They all 4 TOTALLY look different

....And the ONLY one I got Paperwork on is the Costa Ricans, but you and Jeff Ronne are going to tell me that since I don't have paperwork on the others they aren't what I am saying they are...To go back to the original post the guy posted about his Bluefields, anyone with internet access and a little boa knowledge can go to Ron Trempers sight and compair...what that guy has is Bluefields, NOT COLOMBIAN...weither or not Bluefields are legit is another story...I personally don't think they where a big hit, thats why the guy is having trouble selling them...But thats a whole nother topic..
You can visually look at your Roatan Firebelly and see they are totally different than ANY other BCI locality....so why would you question it...???
The Question I always had...was Sonoran Deserts TOTALLY look different than Hog Islands....and Cay Caulkers look Totally Different than Costa Ricans...Why aren't they a seperate Subspeices? Pearl Islands have thier own Subspeices status, and to me they are just as different as the ones pictured above...I guess I am one of the ones that likes to keep species seperate not CLUMP they all together under BCI...Becuase to me they are Completely different, They all attain different lengths, different head structure, Different Coloration, Different Attitudes (Generally), Different Body Structure, Just about everything that would classify then a seperate subspeices they have it...but for some reason everyone wants to clump them all into just BCI....
I find the people who tend to clump all of them into BCI are the people who are into Morphs...When you combine localities into morphs the out come of the non-morph offspring are going to look somewhat in the middle...HogxHypo comes to mind...the normal offspring are neither Hog Islands NOR Colombians, but a cross between Hog Islands, Panamanians, and Colombians, cause most hypos are PanamanianxColombian Crosses....I see many Hog Islands advertised that I wouldn't consider to be Hog Islands but Hog Crosses, and I can Visually see the difference...I recently saw Pearl Islands advertised, and the major selling point the seller had was "Hurry...Add them to your Morph Project and produce something new"...I just about had a heart attach, WHY IN THE WORLD WOULD YOU BUY A PEARL ISLAND AND MIX IT WITH A MORPH!!!!
Sorry about the rant...and long post...But In my opinion you can Visually see differences in the locals, and the longer you work with them, the easier it is to tell the difference...its MAJORLY different in my eyes...
