............well either is not the most effective way to bend a pole. FULL is where it is at, lower (equal) demands on any one area of the pole, less likely to break AND smoother in all aspects. If you demand great amounts from one area of the overall length of the pole and little to none from other areas of the pole you are not fully utilizing the poles potential. SO if a manuf. is designing a pole that lends itself to bend higher or lower there must be a reason. The Skypole has a lower sail thus some say it is a pole that bends low.........NO it is a pole for athletes that load a pole low irregardless of the design (beginners - intermediate vaulters). The more advanced need a pole they can grip as high as possible on and still roll it over. That, in a perfect world, is a pole that bends FULL because the distance from the tip to the top hand is as short as it gets without demanding a large area of bend be isolated into only the top or bottom of the pole which is usually forced there by the poles design (low sail = high bend). It forces the majority of stress into the weakest areas of the pole. So how do you not break that pole.........grip lower and use a stiffer pole.........well that goes against what you are trying to accomplish, grip as high as possible on as big a pole as possible.

Degree = P.E. (go figure)
[color=blue][b]Could you give us a little more info on your comments. As it stands, I disagree with what you say; however I believe you may be referring to another aspect of the pole and your statement might be accurate.
As I read this and comprehend:
This is how we see it
If a sail is lower it will be stiffer in the butt, the energy stored into the pole would not bend the pole as much in the lower portion of the pole due to the design shift from its previous position. (thus a higher bend not a lower bend????)
If you lower the sail and tighten the angle to a point you will still have a pole that will be stiffer in the butt and will not bend low unless loaded incorrectly. (All things being equal)You would get a pole that is easier to “bend overâ€Â
