Tony, 

Will you be using this for visualization or computation?

If visualization I would recommend the 1KM image/product
If you want to do grid analysis, the 6KM grib prod is the choice.


FNEXRAD   rad/NEXRCOMP/1km/n0r_2

for the 1km "image"

size:1778208 ~1.8Mb

about every 10-15 minutes.

or  

FNEXRAD   radar_mosaic_national 

for the 6KM gridded grib product, and then pipe to DCGRIB2

size:111916 ~112K

about every 10-15 minutes.

Garp_defaults in 5.6.f will accomodate these data products

I am not quite the GEMPAK guru as Chiz, but this should help you..
