My SPL is 13'4" and my J is 13'6". I used the spin pole to pole out my 155% genoa running wing and wing, and it stretched the sail out flat. Couldn't have done it with my 135% genoa; the spin pole would be too long for that. Using Rick's calculation below (optimal whisker pole length is 80% of LP), my spin pole is ~4" too long as a whisker pole for my 155.

I’ve always understood the optimum length of a whisker pole is 80% of the LP of the sail being poled out. 80% of a 150 would be 1.2xJ. So if your J was 10’, as on a 27V, the spin pole would be about 24” less than optimal. On my 38 mk2 (J=16.3) with a 135, the difference between the spin pole and optimal whisker pole would only be about 15”.
