I agreed you, 460cc is big head for me. So I like 46" inch graphite with 460cc big head. It will longer distance and more forgiving sweet hit! I have three driver are all 8.5 loft is tour. I decide i've straight with 8.5 loft. I dislike mix number loft driver. There proshop not have drive 8.5 loft tour. that's why I ordered special and modified custom my drivers.
I used 400cc to 430cc head drive with 43" to 44". I sold it.
If you cut down shaft that 43.5 or 44" cause you will lost distance however
more
accuracy
and control.
