Shaft options for cobra amp cell

[cobraman1]

I recently purchased a cobra amp cell driver off the rack with the standard regular flex Fuji fuel shaft. I want to change out to a stiff or possibly extra stiff. Any shaft idea? I would appreciate any feedback on a good shaft option for this club.

Going to need more info.

What's your swing speed, ball speed, are you looking to hit it lower, higher, spin it less, stuff like that.

Well in mph I think swing speed around 110-115 mph, ball speed high 160 low 170's. Way to fast for reg shaft anyway, have never run a reg shaft in any of my drivers. If I slow up with this new driver it launches very high of course because if the reg shaft but I am impressed with the length I am getting out of it even though I catch it a lot higher than my old driver. Have never really played around with specing drivers to much was lucky enough to be fairly long of the tee and just had off the rack stiff and extra stiff. Am playing my best golf in years and striking the ball well ATM and would like to get the full potential out of this new stick, so any info would be appreciated.
