I never grouped with anyone except to help out a few friends with their quests. I did spend some time soloing a few flashpoints just for personal enjoyment, but learned the gear wasn't worth it at the pace I was leveling. I almost always did the SI series twice with both toons (tank and heal spec, it was faster to do instead of solo).
I'm currently working on a merc/sniper duo taking the above into account and it seems to be going fine level / content wise.
Edit: from 30+ I leaned it was good to have your inactive companions out running missions to collect mats. When I hit 50 I had enough mats to lvl up to 400 on each and some left over to supply other folks. I'm currently doing that on my new team as credits permit.
