I'm going to my guitar lesson in 30 mins., and I need some new strings. I usually use D'addario's, but I feel like getting something different.

What should I go for? I would want something that'd last, and have a good sound for metal.
i use ernie ball RPS 10 gauge and i play metal from metallica to BFMV

they are the best ive ever used and ive tryed alot
