Are LDS's Needed On 7' Tables?

[Johnnyt]

I have a 7' BB with 4" pockets. I also have three LDS's and four regular shafts for seven different cues. I see no difference in the amount of balls I run switching back and forth between lds and regular. Anyone feel differently? Johnnyt

Basically once you know the pivot length and BHE to make a shaft compensate the arguing points are not as clear... On a 7footer the precision difference may not be enough to miss balls regularly.. What I would anticipate is that the non engineered shafts could miss balls because of radially consistency from time to time but for a bar box player even those balls may find their way into the subway.....
