The reason a whisker pole varies in length is so that it can be used with different sized jibs. Just using the spin pole (or any fixed length pole would be somewhat limiting. The length of a whisker pole is not a function of J because it depends on the length of the foot of the jib and the height of the clew. If you want to pole out a jib and not use a spin, just trade the pole in. A whisker will work way better.
There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries.
Shakespeare, Julius Caesar IV, iii, 217
