I haven't noticed much, if any, difference in the durability of MSV 1.10 Hex mains and Gosen Micro 17 or Gosen Micro 18 crosses. Conventional wisdom is that the Gosen Micro 18 is not going to last as long, but in actual play I haven't noticed a big difference in one over the other. I still get around 10-12 hours out of the hybrid.
But I use a dense string pattern racquet (18x19), don't play with extreme top spin, and none of my racquets are leaded up to high swing weights. So take it with a grain of salt.
Also, MSV Hex feels and seems to play (at least for me) much better at lower tensions - which is also what the manufacturer recommends. I string a full bed around 52lbs and a hybrid at 52/54lbs. So if you try it higher and don't like the feel, you may want to drop a few pounds before you give up on it.
