If I have six florescnt lights and feed the first light from a J-Box with 1/2 in. flex then jump from light to light with 1/2 in. flex, should I consider all flex as fixture whips?

Your installation is fine unless you were to use 3/8 FMC. Then the length could not exceed 6'. Fixture whips are defined in 348.20(A)(2).

I must admit that I've never even seen the 3/8" size FMC for sale.

Here is the explanation from the 2005 NEC Handbook:
Section 348.20(A)(2) makes it clear that 3/8-in. flexible metal conduit is permitted to be used as the manufactured or field-installed metal raceway (1.5 ft to 6 ft in length) to enclose tap conductors between the outlet box and the terminal housing of recessed luminaires. Flexible metal conduit is also permitted to be used as a 6-ft fixture whip from an outlet box to a luminaire.
What this is saying is that a piece of 3/8 FMC can be used to wire from the junction box to a fixture. This conduit would not require support or securing in place if 6' or less in length as stated in 348.30(A) Exception No. 3.
