The two most common suggestions are to go either scavenging/cybertech/underworld to create your own mods and armoring for orange gear, which allows you to save commendations for enhancements, or to go slicing/scavenging/*insert profit skill here* to make creds.
With the former, you also get to gear up your alts with this method as well, as long as you find adaptive armor for them before hand.
I appreciate the reply. I've considered cybertech already and have decided i would do that on a smuggler that I've made. I'm more interested in opinions of biochem, artifice and i suppose synthweavings usefulness overall and for pvp. Though the 3 gathering skills does sound appealing.
