I go with what the rest of my teammates are doing. I honestly don't run strikes that much, just do bounties and then go to the crucible. If I'm on with my buddies we're usually setting up for a raid, so I get my experience in to level up my ballerhorn... I haven't done a ton of bounties just because I only need the pocket infinity, so as soon as I get that I'm only doing bungie when I need experience.
