Yeah I agree with Vio. Fury is best for any kind of general training/slayer, but if you're doing NMZ or chinning the zenyte jewellery would be better if you can afford it.
I would say that if you're unsure whether to buy and don't have a huge amount of cash to burn then just wait until the price drops a bit. MM2 hasn't been out all that long in the grand scheme of things.
