I have two Jacoby Hybrid shafts... one is 11.75mm w/ Tiger Everest tip this shaft is 30".
The other shaft is a Jacoby Hybrid but its 12.75mm w/ Kamui Clear Medium tip and the shaft is 31".
You can choose which shaft you want. The 12.75mm is brand new and was shipped to me from Jacoby last week. I did chalk it to try it out but it hasn't even been played in one game, its actually worth more than the 11.75. Sticker price on that shaft is $310 w/ tip and extra length shaft.
