None play better for me than G2 Diamond Blend. Someone asked about alternatives not too long ago: Zipline Recommendation
Unfortunately, just the one recommendation, but I am going to give it a try.
I have tried a bunch of Zipline strings. Nate Martsolf’s Signature Prestige is the only other one that really stands out to me. Very different feel to Diamond Blend — much softer and fuzzier.
Markmont Formulas are worth a try. Unique feels and they last well compared to other poly strings I have tried.
If I want a low cost poly string, I use One Drop bulk.
