The short answer is "yes".
NBP nearly always correlates with the outermost edge of the curvature of the residual bend of the shaft. Obviously, the more the bend, the more the possibility of it affecting the feel of the club. My whole p[oint in my last post was to get some of the forum members thinking about the relationship between the residual bend of a steel shaft and the asymmetries that they are experiencing in a bearing finder, Dan's or otherwise.
NBP-COG:
There was a question regarding this COG alignment and FLO From Charlie B.
I've built about four woods so far using this alignment and have noted that FLO is out the window. Using this alignment hasn't produced a nasty wobbler yet but it is not the best FLO alignment either. Two of the drivers I built and aligned to COG were offset hosels and FLO was worse. I have since re-shafted one of them and went for FLO. I tried to check the alignment difference once I had marked the club for FLO but the shaft fit was a little too tight to get the head to settle off the end of the bench for a good COG mark.
I personally have not been able to tell if the COG alignment feels better or not. Truth is, I don't have a refined enough swing to judge with. I haven't been able to do any experimenting with our course pro because there are major management changes afoot and I've been keeping a low profile while the dust settles.
Best,
CB

Corey,
My question is, does residual bend affect the performance of a shaft the same as if it were an NBP? In other words, will the assembled shaft tend to rotate toward the residual bend point?
