yeah its with the loop.

i also have the rio and my floater is the same length as the rest of the tips. but its in a 8wt so idk if that makes a difference.

but its a good 40' floating tip? i thnk that would be kinda long for a tip?

and its also very thin almost like a running line...it gradually tapers thicker by the loop just like the main body of the line as well.

that is what makes me so confused
