I fell in love with the Delica first. Got a purple FFG as my first Spyderco and it went all downhill from there
Always thought Delica would be the largest I would want to go for EDC. But I could NOT resist getting the orange Endura when it came out. It's such a fun color I thought it would be cool to no matter whether I would actually carry it or not. But to my surprise, I really liked the Endura and got used to the larger size pretty quickly since it's so light and just works great as an allround knife. And I gotta say I'm a real fan of Spyderco's FRN with the bidirectional texture. Fun colors, feels good, lightweight, cleans well and stands up well to use.
