First off I want to say thanks for sharing this awesome string combination. It's worked so well for me that I've completely lost my desire to try other strings. Now the problem is that it seems the supply of the old IsoSpeed Pro is coming to an end. Have you found a replacement for it? I have a few reels left, but after that runs out sadly I'll have to start experimenting with new strings again. If you've found a substitute I'm sure a lot of us would like to know. Thanks!
