I'm currently level 35 and have an assortment of wands with procs and want to know which one I should really be using.

I had an ice wand for a long time and liked it. It seemed like the freeze proc would combo with my Firestorm, is that true? Then I got a fire pin wand that does a lot more damage AND it has the fire proc but it doesn't combo. Is it worth it to still use the fire wand for the extra damage and fire proc?

And are the curse wands which do weakness worth using if their damage is lower overall?

And what the heck does the frog wand do really?
