aaah, so basically you want a Harald Deathwolf list, there is a link to such a list I created:

and here a some very good potential thunderwolves:

My general rule of thumb, compared to the list I posted is that you should compose thunderwolves at around 260-265pts, as follows:
4x Thunderwolf, 1x Thunder Hammer, 1x Storm Shield (1x Meltabomb). I believe this to be the optimum load-out for Thunderwolves, who will often need a screen (fenrisian wolves) to survive the amount of fire they may attract.
Hope that helped, Good Luck!
