Depends on your ball and spin. Mine was with the level 35 callaway ball and -61% spin. And I find the 8 iron right on if you don't use full spin.Use full B/S and anything can happen
I've got Kats set up at 60Head/40Tail. Pretty identical to using Sine/Cosine (which gives you 154y). Kat's spin for clubs and balls doesn't work.
And to throw out there, using full B/S on PW - 3i will almost Always give you much more predictable and stable shots. Even a little spin will. Random example would be a 6i (fairway). Full b/s gets me 171-173 with my current ball. Spin just barely barely past the chevron on Nike gets me 176-179. Flat gets me betwen 177 and 186 which is obviously a huge discrepancy.
This comes in very hand in CTTH Ready Go's where getting close to the pin is paramount. The only exception I can think of would be extremely high spin rated balls which imho give you more wtf shots than ever.
