Have had a play around with various crafts and heres some random thoughts. Slicing - nice cash + blueprints - not sure if its meant to be this way but the blueprints I get are all for cybertech - tend to be ship components. Armormech/Armstech (and jedi equivalents) - not sure these are worthwhile tbh - gets expensive and people tend to out level the stuff fast - might be some call for high end stuff at endgame but might not. Biotech - awesome! The adrenals/stims/medpacks from this skill are fantastic - even the green versions are good - the blue ones are godly and purple... Only issue is having to take diplomacy to get medical supplies missions (which take 6 mins each at first tier!) to get enough to make one blue product... Cybertech - making mods is nice but I dont seem to be able to reverse engineer them which is odd? The spacecraft bits and Robot companion armour will eventually be in demand tho. Treasure hunting - like slicing for cash if you do the boxes missions but you also occasionally get some nice items. Underworld Trading - can be used to get blue metals/materials used in the other tradeskills and companion presents though rather annoyingly I find if I send my companion off on some mission that says hi tech weapons or something he often comes back with something completely different... Happy Crafting!
