Note that S300 only indicates that it’s a “stiff” shaft, not the model of the shaft. Not a lot of folks play steel in their woods these days.
I apologize for the delay in responding. What I have found is that on .335 tip steel woods, True Temper stated that the tip should be trimmed 1/2″ on bore thru woods, then in 1/2″ increments for each successive wood (#2 wood would 1″, #3 wood would be 1.5″ and so on). If it’s not a bore thru head, then you would trim nothing from the tip for the driver, and then in 1/2″ increments. That was on the Dynamic Gold .335 woods from 1990. Generally TT would have used the same trimming instructions on all the .335 tip steel wood shafts.
