I prefer
Felix. Flint is the thing you use to start a fire.
If you are looking for more F boy names you can click on F near the top of the homepage and then click Masculine to the right. Or you could always search the Name Opinions Board for F boy names and look through old posts.
Anyway to
Felix combos...
