Okay so I have a graphite design vf hybrid shaft I am planning to use on my nike vapor pro fly 3 iron head to use as my driving iron, Im looking to do 39.5 legth the shaft itself is 44″ in length, it looks as like I need to trim almost 4″ of length of the butt is that too much?

shouldn’t be an issue. the VF is butt trim only, taking into account bbgm, you’ll probably have to trim a bit more than 4″. Dry fit first and measure. you might need to bore out the hosel on the nike head also, I think it’s .355.
in your previous thread, you said the shaft was 42″ long, still might be okay, but as mentioned above dry fit first, measure before you cut.
