Cheap, crisp syn gut? OGSM 16, I personally found better spin and feel with the thicker versions than with the 17g. I prefer to cross it with 17g Forten Sweet. I found surprisingly good spin with this set up, but it lasts all of 1.5-2hrs before losing it all: that crisp response, spin, and tension - basically it goes to mush. That's just how OGSM is.
