Torsen diff for hyper 7 Vs. Hot bodies Lightning diff

[shawn197]

I am thinking about upgrading the differentials of my E-Revo with a Neu 1515 1.5y/s. So I been doing some reading over the Internet. While I was lookin at stuff, I found two candidates for my E-revo. One is Torsen diff for hyper-7 and the other is Hot bodies Lightening diffs. Which one should I get? Of course I know that I need to get diff cups, pinion gears and bearings with them. I have a budget a little over $200. Please, help me with it, guys.
