before i sent my MP 66 for warranty i had it strung at 24 pounds 1 pice stringing. my stringer thought it was too high but who cares..... stringing tension is your choice and depends on your skill. 22*24 or 20*22 is good place to start at.
at least 25lbs, then up 1-2lbs at a time, when u fell u lost in many games ever than before and u feel play bad alot, it's looks like the tension too high
