I've played in polys in the 25 range. Wilson Enduro Gold... has to be one of the worst strings ever made. Stiff as crap, and feels like fence wire to the touch. I used to use it on 18x20 blade 93's so that anything else i strung would be a cake walk.
I strung it up in a o3 tour MP at 28 pounds for !@#$'s and giggles. I've never been able to hit the ball so consistently. Pulled it out the next day to play my friend and it felt like crap and I could barely get a ball in the court. I'm not sure if you'll get the same results but I'd guess you'll have to cut it out the next day.
"I knit with fence wire for a living" .... its as exciting as it sounds.
