I agree with orange, the yellow and black towels are the same as the Jr.s. I do think that the cobra Jr.s lint more the the yellow and black. Maybe its just me but it seems all my Jr.s lint a little bit from time to time.
I think the Jrs. aren't as nice as the black/yellow CGs. First of all, they lint like a sheep but they're also not near as soft. I am now washing my CG black/yellow towels seperately from all other towels. Don't want to take any risks! When I buy my CG MF Wash, I'll see if I can revive my Jrs.
To everyone who bought the purple linting Jrs. from AG, I wrote them about it and they replaced them with other MFs for free and let me keep my purple Jrs.
