Best bcnm for your orbs?

[valron]

i have a large amount of bcnm seals and no experience with the battles themselves, i would like to make the most i can out of the 150+ beastmen seals i have and the 200+ksnm seals i have.

anyone know what bcnms / ksnms i can do with proper gearing of any of these jobs?

jobs that are around 30~ blm nin
jobs close to 20 ~ pld rdm mnk
would it be easier to level something like blackmage or rdm or pld to get better drops from better battles?

level smn to 20 for Shooting Fish. its soloable, only costs 20 beastman seals, all you need is smn 2hr, Ramuh and a yag drink. a mannequin head (30-40k) always drops, and you have the chance to get a mannequin body (300k+) and a thunder spirit pact (200k).

also for anyone with smn or bst at 75, Contaminated Colosseum is worth a look. Its a ksnm 30, beatable by 4+ smn using Garuda and Predator Claws.
Notable drops include Orichalcom Ingot (300k) Damascus ingot (300k) Damascene Cloth (180k) Adaman Ingot (70k) and Cassie earring (650k). Also note that the ingots have a different drop group from the cloth and the earring, so you could get multiple big money drops in one run!
