Tip cut for Motore Speeder VT

Motore Speeder VT is not in the official custom options.

So I bought an after market shaft as well as pulled out OEM sleeve.

Do I have to make 0.5 inch tip cut to get the true flex ?

What's the guide line from titleist and fujikura ?

Thx

Junwon, 

All of our custom shafts are tipped 1/2".
