Thanks to all for the input and information. I have the performance sheet but there is no spec on the x dimension. I think at this point I am going to a set of 1 inchers from B Blades. I'll post the results afterwords and perhaps it will help another get dialed in.

If you really wanna get technical the X dimension is the measurement from the crank to the bottom of the boat..I learned that the other day

Put 6 blade Herrings on you'll love it.
