FE/FC What size spoke wrench?

I want to purchase a spoke torque wrench for my '15 FE350 but I do not know what size fits the spoke nipples. The owner's manual lists the spoke nipple thread size & torque specs, but not the size of the wrench needed. A few of the reasonably priced torque wrench kits come with several heads up to 6.9 and I have a dual spoke wrench that came with another bike with sizes 6 & 7, but neither end fits my Husky spokes, which leads me to believe they are bigger than a 7.

Thanks for any help!

I use a Tusk kit and I believe it's a 6.9. Always remember to set back to "0" on the wrench
