This is a perfect running line for the ones who want to know where their fly is. This monofilament core running line has an orange HiFlo™ – coating with dark green markers in 5 m intervals. So you can easily see how much you have line out and if you get a take it’s easy to cover that lie again as you know how far it was. The monofilament core makes it slightly stiffer compared to our other ACE running lines so you’re less likely to get tangles. It has a big loop at the front and smaller at the back and it’s made over a 30lb core with total thickness of 0.039”.
