Thank You Ken and Cathi. I guess I still have one confusing mind cause I maybe don't understand parallel tip as much as taper tip which is generally backwards perhaps. But if the shaft has a 4" tip not 3", how do you install it. Do you install it thru the bottom and cut and trim from the bottom of the head, or do you take an inch or so off before installation...or neither. Just install it as is do depth pre-angled cut with no trim at all of the tip. I don't understand how a 3" or 3.5" or 4" tip insertion could possibly play the same. I guess all shafts are different and therein is the research I need to be doing. But I was told by Grafalloy that no tip trimming was to be done so apparently shaft is also designed to go into Titleist bore thru, and to be tipped for standard bore. Let me say it this way, I guess I thought parallel tips were made to be trimmed to fit the insertion length, and that is where I was misinformed. If the bore was 2.5" I thought you removed 1.5"(with a 4" tip) or if bore depth was 3.5" you removed a 1/2".  This is where the comment that shafts were generally 3.5 to 4" tip in this clubs made me want to be sure that there was no difference in the recommended tip length. There I just muddied up and made myself sound even more lost, but I am  not I get it now.

We used 3.5" to 4" parallel tipped shafts to build our bore thru drivers.  The shaft was inserted through the head, the excess trimmed and the end filled and buffed.  The length was trimmed at the butt end of the shaft. These shafts were built for our bore through heads so you may want to inquire with Grafalloy about using the full parallel length of your shaft on a bore thru head.
