OK, the Copperhead and all other Brunswick balls don't have the advertised core in under 14 lbs, so her ball has a "lightbulb" core. Not a bad core but it does seem somewhat of a ripoff to pay the price and not get the advertised core. And this is not unique to Brunswick, the advertised cores can't be used and still get the light weight. It just seems to me that there should be a price reduction when they change cores.
I would suggest a pin to PAP distance of 5", positioned above the finger holes if the pin out will allow that, and with the cg positioned to give 1/2 - 3/4 oz of positive side weight so a balance hole can be added if desired. Have her try it, and if it breaks too early, which it probably will, have the pro shop take it to 4000 Abralon and polish it. When she trys that, you'll have the two extremes of reaction and can change to somewhere in between as desired. Good luck, and let us know how it worked. -- JohnP
