Very late getting to this, sorry.
I took all powers from primary and secondary on my Rad/WM
I assigned 36 extra slots to primary and 24 to secondary.
Since you're asking about WM specifically:
Bash 1 slot - I put the Chance for +Resist ATO in there, only really throw it when beating down bosses who can hurt you
Pulverize 5 slots Gladiator Strike, I like the set bonuses
Jawbreaker 6 slots Kinetic Crash I highly recommend this as it is a most useful attack when you exempt down. Plus lifting up baddies off their feet is signature of the set, makes it fun.
Taunt 1 slot
BU 3 slots
Clobber 5 slots, 3 Hecatomb, 1 Absolute Amaz Stun Duration Purple, and Rope a Dope Acc/Stun, again a signature power of the set. I have always played WM even back when clobber did no damage on live. Can't imagine playing this set without a long duration Stun.
WM 4 slots Superior Gauntleted Fist
Shatter 4 Slots, 1 ACC IO+5, 3 Armageddons
CC 4 slots Scirroco's Dervish
