I’m converting some Titleist T300 heads from steel to a graphite shaft. The hosel bore depth is 1 3/8 inches. I’m adding weight with the 8-10 gram rubberized tungsten weights.  The weights have a 1/4 inch end, then are cylindrical. My concern is the shaft adhesion I’ll have on the remaining 1 1/8 inch after the shaft is installed. That’s the amount the shaft that will be touching the inside bore of the head. Is that amount enough?

I’ve taken a look at different kinds of weighting but tungsten seems to be the way to go.  Thanks all.
