hoto is good to use because hammer gets a lot stronger but wiz is also good becaues if u are low on mana u get alot and u also get more fcr and u get hig res so just your choice, i ues hoto because i can still get max resistance withou wiz and i have bo and i use frostburn and so i have enugh mana and also i dont notice too much difference in fcr so thats why i use hoto, IMO i say hoto
