hi,

I have a new Diamana that has a rectangular notch on the butt. I'm led to believe this marks the spine of the shaft? It's in the same line as the logo.

1- Can someone confirm that this is indeed true, without a doubt?

2- If this is true, aren't you suppose to orient the spine at 9 oclock or facing the target?

If this is the case then it won't be logo down.

3- What are the effects of having the spine at 12 oclock?

thanks

Jack

notch down ... logo is down. I have a Whiteboard 73(S) x5ct in my driver and Redboard 83(S) x5ct in my 3wd. Can't tell ya more then that.

With the face/top line of the club being 12 o'clock, the logo is approximate 2 (points to the right) being a right hand club. I asked the fitter to find the spine and this is the result.

Here's what know for a "fact." I live relatively close to MRG so I phoned them before having my clubs built. I was told Diamana's do NOT need spining. Put the notch down, the label ends up being down; that's it. If some fitter comes up with something different - all I can say is, "I choose to believe company staff before any club builder, fitter or for that matter anyone online." good luck.

not sure the notch is anyting besides where the shaft was held during painting etc.. or cut off to make length. but i just hand rolled a white board 73 stiff in a spine locater - and the logo - she was facing down. or 6 o'clcok spot during installation. a few came in like that. but MRC can lead you in the right direction. solid company..

I have handled 6 Diamana shafts in my shop (2 Blueboard, 4 Whiteboard) for competitive low handicappers. Even as great a shaft as Diamana is, each shaft had its own characteristics as to NBP, Spine and Flat Line Oscillation (FLO) which did not all line up with the label down. If you do not get a good Pure/FLO, you will get shaft warp and the Driver toe will droop. Toe droop is not exactly the position that the Clubhead Engineer had in mind to deliver the head to the ball. Here are my findings: Swing speed "less than" 110mph, put the NBP at the 9:00(down target line) and then get a good FLO. For swing speeds above 110mph, place the NBP at 12:00 and, again, get a good FLO.

I have talked to most of the Techs at the Shaft Companies and when pressed, they "all" say that each shaft will be slightly different and that the specs change when installed in bore thru's, tipped, and/or butt cut to final length, all of which change the cpm's, the NBP's and Spines. So, with my customer base being very discerning and critical, I must get it right, so the standard "label down" doesn't always fit.
