Thanks for the responses fellas. I've done a little research and I think it's the Teeny Pro Series Flip Pallot line (85ft; orange) that was developed a few years ago.
I wanted to know what line it was so that I would be able to determine what applications it would be best suited for. I've tried casting it (no fly) on the 13wt rod in a field, and I think it casts fine, but how it behaves on water with a fly tied to it may differ (especially with wind). Now that I think I know what it is, I'm better able to determine where its use is most appropriate. Perhaps sight fishing for tarpon, but not great for deepwater applications. Thanks again for your input.
