headlight fluid

Sups I've been playing CS for about a year, and I regularly play on one certain pub. What I'm wanting to do is find a few small hacks, like a wall hack or no recoil, that I can use to basicly mess around with on a different pub or pubs when I'm not on my regular. I know where to find them (google made it easy enough), but my question is that I know there are a lot of different ones to choose from, so do you all recommend any particular ones over another? Thanks
