Fixing hardwood screening

[DEVLPA]

Will be fitting 42x19 Kwila battens as screening to a deck, fixed to 45x45h/w & 68x68hw posts. What would be the best method to fix (coil gun/finishing gun/screws etc and what nails clouts/decking nails etc etc)

Photo of proposed battens attached.

Thanks

I'd go for screws.

Might take a bit longer to do, but will give the best holding power.

how about a 50mm Gal batten screw in each end?
