Ah. Yeah Venezuelan's arent a very common BCC to be found. They arent super rare though. From what i have seen, they seem to be on par with stuff like BCL and BCO. If you are looking for pretty obscure boas, check with Chris Wolf. He breeds a lot of those less common boas and most of his stock is from either Gus Rentro or Vin Russo as him and Vin are friends.
You need to pick yourself up a BCL. They are harder to find overall but they are really pretty. Louie is my BCL from Meltzer/Lincoln line which i have been told by a few people that the line is almost gone and not many are around. Mine was from a Vin Russo and Joel Diaz combo. Check with Jessica Fee if you are looking for Denton line stuff as she has some awesome looking ones.
