My favorite types of PTs are about my player as a character instead of actual stats.  It's really fun to come up with dumb stories about Slip McScruff and it feels less like a homework assignment.  When it's just about character, I don't have to do any research and I pull on some dumb thread until I hit the word count.  For example, we had a PT about tv appearances and I came up with this whole thing about being caught on Cops.

Those kinds of prompts involving other players are also fun when you can choose who to write about.  Usually when a WFT is to write about the post above you, I have to stalk the thread until I can actually post.  The one about what is this person as a drink and sandwich was especially tricky for that, while the one about continuing the story from the post above wasn't so bad.

When it's about stats, I find tasks about my own skater or my own team to be easier since I know everyone involved.  Sometimes writing about other peoples' stats can be kind of awkward because I don't know them or their career.  On the flip side however, when I was in the cup finals last season, I loved reading all of the CW tasks talking about me from people I never talk to.  Stat tasks where you can learn some league history are cool as a once in a season kind of thing, like the recent one where I got to dive into Izzy's chance at breaking the hits record.
