I also tried Discho Microfibre and found it to be a very good string. It just seemed to go mushy after about 10-12 hours, but that's already a lot of time for me. It's worth trying and the shipping is free.
Although I like Mantis Comfort Synthetic, and it's only $9, I can't recommend a string that I break in under 5 hours. But if you don't break strings it might work for you.
