David,

IMO, as long as the weak axis is aligned on the swingplane, there probably isn't a lot of difference. Sometimes, if the N1 is on the wrong side of a strong S1, I'll put the strong S1 at 12...then, in that case, the N1 is away from the target and N2 is toward the target. But, I do prefer to align N1 to the target because that's the way the shaft wants to align when it loads. As I said in my reply to Dave yesterday, John Kaufman describes why well, I think, on his website. Here's the quote: "In a spine tester when the shaft is bent it will attempt to rotate such that it is being bent in its weakest direction. During the swing, the club for the most part bends in the direction of the swing plane. If the weak axis is lying in this plane there will be little tendency for the shaft to rotate during your swing as it does in a spine finder. I don't know how strong this rotational tendency is but why not minimize it?" I read this as suggesting, minimize ovalling and a you'll get a tighter impact area on the club face. Another quote I took from John's web site is interesting as it relates to your question. John describes a test in which he used two shafts, one with a spine at 250 cpm aligned to the target and one with an NBP at 250 cpm aligned to the target and reports on the test. Here's a quote from the end of that text: "One had a weak axis of 250 cpm (other axis at 258) and the other a strong axis of 250 cpm (other axis at 242). I built two identical drivers with both 250cpm axes pointed at 9:00. In one case the strong axis was at 9:00 the other the weak axis at 9:00. I tried a blind test and the weak axis at 9:00 was definitely the preferred alignment.

What do you do with these shafts? I like NBP to target for above reasons. If the S1 is opposite, I don't check any further...and the club always seems to perform well. If the S1 is 40� off, I'll probably locate FLO to see how far off it is. If significant, I'll go with the FLO. Usually, though, l find FLO isn't far off of the NBP-to-Target alignment. If that's the case, it probably doesn't matter. Bernie Writeto: [EMAIL PROTECTED]
