Fly Line ID.

I need some help. I picked up a used Ross Evo 2 on ebay and need to identify the line it came with. Its that optic green SA color with a very short (5ft) pale grey tip. I think it may be a GPX with a midge tip. I can't find it on their website. It was used on a 590 ZXL. The line is in great shape and I would like to know what it is before I dump it. Thanks.
