913 Heavy weight Fairway Metal Shafts?

I noticed you only offer one shaft in the 90+gram range which is the Pro Force V2...I am looking at getting an 18Fd and need something in the 90+ gram range that has a low/mid or mid flight...any thoughts? or options I could get from my Titleist Dealer via special order?

Thank you!

This would be for a 913Fd 18 degree metal fairway...any input would be appreciated.  I am using the 86 gram Pro Force V2 in my driver...

Thank you!
