Spoke wrench size

Which spoke wrench for the std 12 mm brass nipples supplied together DT
Swiss Competition DB?
1)0.127 (3.22 mm)
2) 0.130 (3.3 mm)
3) 0.136 (3.42 mm)

Neither information from the DT Swiss website nor answer from them after
my e-mail. The italian DT Swiss service (!!!) office does not sound as
well informed (he thinks !!! 3.3 mm). Park Tool website says DT requires
3.22 mm.
Thanks.
