f6 or f6f loom?

LOL I didnt see that when I was looking on there site under split loom but if you notice they are selling 4ft for $26 plus shipping and I plaid less than $25 for 30 ft. I would consider that price if its the 1400 deg loom but if its the same as what I bought thats a rip off.

if you read it that stuff was 2 inch... this is the painless stuff for 23 bucks and i think the summit stuff is like 18...
