Nike SQ Machspeed Black set up questions

[bishop952000]

So I'm thinking about purchasing a Nike SQ Machspeed Str8 Fit Black and am wondering if I can use the same wrench and set up book from a VR driver?  I currently play a 9.5* stiff Ping K15 (the fitters, a kid, recommendation, which I now regret) (SS 104-110) and i like a lower to mid ball flight.  The Nike I'm looking at is a 9.5*  and a Stiff Flex Matrix Ozik HD6 shaft.  I've done some checking on this shaft and found that for my SS I should hit a Strong Flex   I've never swung a Strong Flex, so would a Stiff Flex be ok for me?  Is my ball flight going to be low low with a 9.5* w/the Ozik?  Should I try and find a 10.5* with the Ozik?

Any help is appreciated, thanks.
