Need Help Finding Trim Code for Older Shaft

[Ted12345]

This goes out to the old timers out there.  I have what appears to be a True Temper Flow Flex driver shaft. It is unique in that it has a 5” midsection with small, 1/2 inch sections.  I’m looking for the trim chart code for this shaft. Looking to try a steel shafted driver to help me find a fairway one in a while. 
Thank you.

Golfworks may have that info in their archives.

That one is going to be tricky. Feel like I have a vague recollection of a shaft like that but really not sure.

Not sure tipping specs will even be useful on a shaft like that if you are trying to match it up with a modern driver head. The head weights are much lighter now so the tip trimming guide for older stuff goes out the window since they were gauging off a heavier head and shorter play length.

My best advise would be to install without tipping and play it an extra inch longer. Grip down to where you plan on playing it and see how it reacts. If it feels too loose, you can go back and tip trim it down. If it feels okay, you can then butt cut to final length or just keep gripping down.

I somewhat recall TaylorMade did something similar with the "Bubble Shaft" back in the 90's
In todays terms, it would be considered a Mid Range flex.
Steel shafts in drivers are seldom used nowadays, while some players still prefer the flex feel of steel shafts.
It basically boils down to achieving the launch and kick point during a players swing.
One drawback will be the loss of the shaft twisting of the older shafts.
