The way I look at it is a little different, I am very grateful that the TJ's and LJ's still get the attention from aftermarket manufacturers that they deserve.
Long arms are great if your terrain calls for it. While it is not for everyone 4 link is the way to go if you want to build a low cog street friendly trail killing Jeep TJ/LJ.
I hear alot of Jeep owners talk down to the rock crawling crowd/cralwer fans. If you are going to hit trails on the East coast or in the South chanches are more than likely you are going to run into rocks.
