If it is any help, the 910H is 41" for the 17 and 40.5 for the 19 (57.5 lie angle for the former and 58 for latter).  At golfclubspec.com, the 585H 19 deg is 40" and 58* lie angle.   Safe guess for the 909H 17*  would be 41" (you can always shorten it if too long).

Thanks.  I'm looking for the uninstalled length of the 17* 909h.  

Cathi or Cameron - do you have those uninstalled specs for the shaft?
