So my main PC is all Nationals. I have now accumulated lots of cards but also a lot of doubles. If it was cards of your favorite team would you keep the doubles? Would you trade them? I would end up taking out the ones of player and designs that I like. 

I'd trade them. You can always flip those doubles for cards of Nats that you need. I know there are a few Nat collectors on here as it is.

I do this with my BoSox. If I have it for my sets and/or PC then I put the dupes on my traders.

PC collection is Cleveland Indians/Guardians and like you I've accumulated plenty of duplicates.  I have little to no desire to keep extras of a card so I will typically trade/sell them.  I've only gotten a fraction of my duplicates listed on here, but it is on my agenda to do so.  The only reason I have kept any duplicates is for overlapping coverage.  For instance I have also started to build sets, so if I also need a particular indians card for a set build I will hold on to a duplicate for that purpose.

I definitely want to trade them and get more Nats. It just feels like a crime to me by getting rid of my favorite team though.

I keep mine unless I find other collectors who need them. I'm completely new to trading on here but trade fairly regularly on Twitter. I have a few buddies who I blind team trade with due to differences in fav teams. For instance any dupes outside of a set build of Phils cards, I send to a buddy in Philly. He does the same with his Braves cards. 

I like to keep cardinals dupes.

I like to make team sets, even if I already have.

I will trade an extra occasionally if someone is close to set completion.

I get that, but think of it as helping another collector getting what they need for their favorite team. Both sides win and the cards get loving homes.

I keep building extra Dodger team sets.

All of my dupes go in my trade box.

Unless I intend to get them signed TTM or will build a second set with them, my duplicates are all FST.
