If we're talking characters , I'm gonna buck the trend and go with Linda Park for practical reasons:
1)Caitlin- While sweet, smart, and loyal, she's engaged to a guy who can burn your from the inside out and is likely the kind who wouldn't take kindly to chasing his Fiancee'.
2)Iris- Has a cop for a father and a cop for a bf , in addition to being hung up on a guy who can run faster than the speed of sound and a friend who's loved her since childhood. Too many dangers and complications.
3)Felicity- Also hung up on a border crazy and needy guy who's barely hanging by a thread and would likely stalk during your dates, in addition to having a rich BF who can fly.
4)Plastic- Any relationship with her would likely be explosive
5)Lisa Snart- While she's got the whole sexy bad girl thing going, she's way too unpredictable and having a jealous Heatwave chasing you with her Captain Cold Brother would be problematic
6)Peek a Boo-- While she may be a good time and is loyal, she seems like the type to disappear once things start getting heavy.
So , Linda Park is the most attractive. She's not looking for something serious. She likes to have a good time. Can drink you under a table, and she's funny, cute, Plus , she's actually single unlike most of the other characters on the list .
