help me flist you're my only hope

I'm trying desperately not to overthink what fandoms/ships I should offer for chocolate box, but overthinking is my middle name. The way I see it I have two options.

OPTION A
Offer only to write for fandoms and ships I'm so comfortable in that I can happily write a million words for -- knowing that I'm likely going to struggle to fill the required four fandoms and two ships each rule against the nominated tagset.

OPTION B
Offer to write for any and all fandoms and ships I'm comfortable with only because I know that I can at least meet the 300 word minimum required for this exchange -- knowing that someone might be a bit let down if they only get a tiny assignment fic.

Anyone have any opinions about this? (^_^;)
