Been riding the CI uprights lately. Must say of all the upright style fins, these have a small dose of flow through them.
Most upright style fins don’t and in fairness is difficult to incorporate, cause it contradicts what upright fins do, which is pivot.
Oddly enough these fins are actually more upright degrees wise than many others.
Had these fins for a long time, just never put them into daily mix.
These finally might make the cut into it.
