rock crawling

Now that Shrockworks is no longer making sliders, what sliders are you all running? If you don't have sliders yet, which ones are you considering in the future? I am looking to get sliders for the ranger, but not sure where to put my money. Lets see and hear what you all have to say!

I've heard that lift blocks are more for show and a bad idea if you plan on really off-roading with your vehicle and things such as rock crawling. Is this true?
