Length vs. Weight

[RPVA03]

With poles of different lengths but the weights are "equivalent” (ex. 13’ 170 and 14’ 150), if you HAD to, which would you say is the bigger pole, the longer pole or the bigger weight? With the same grip on each pole and with different grips.

If you're holding at the same spot or not, the longer pole is going to be the "bigger" one.

If you grip down on a long pole, the sail piece will be higher in relation to your hands than the shorter pole, and due to this it will take more energy to bend but also give you a quicker recoil.

If you grip higher up on the long pole than the shorter one, it will take more energy to get the pole to vertical and will take more energy out of the rotation by bending a greater distance, thereby requiring more overall energy within the vault.

If you grip higher up on the shorter pole, then you're essentially stiff-pole vaulting with the longer one.

Unless, of course, to say that the poles have different manufacturers, which is another story

Length vs. Weight Good rule of thumb
it is always important that you feel or realize the difference between weight and lengths of poles!

Take a 14-155 and a 15-155

Holding 6" down on each will feel the same however the longer pole will be stiffer and here is how you can tell!
as you move your hand down on the 15' pole it gets 1 lbs stiffer per inch decrease of grip.
Holding at 14' the pole will be much stiffer.
It is best to jump on a pole 15 lbs over your weight before moving to the next length size pole so the longer one can be under your weight.
example
if you weigh 165 and you are jumping on a 14-180 moving to a 14'7"-170-175 will be the next progression.

The integration from on size to another on ESSX is use the power number this is in kilos!
2.2 lbs =1 kilo
so if the pole is a 180 which is 82 kilos then going to the next length you subtract 2 kilos so you will be on a 80 kilo which is a 176
or if you are not clearing over your handgrip you should look at a 169-173.
