Difference between RSL and NR in chick

[hangin'witthepeeps]

What am I looking for when I go to TSC in order to get RSL or GSL instead of the NHR. I can tell the RIR because they have the dark brown on the wing tips. Does NHR have dark also? They have a few golden ones with red racing stripes down their backs and white wing tips. Are these GSL?

the ones with the stripes down the back are probably sex links

When I bought RSL from TS, the redish ones were the pullets, the yellow ones were the roos.
