Rob,
I didn't upgrade my steering until it was pretty toasted, but wish I had sooner.
As stated, the tie rod adjusters are weak points. For wheeling, this is a sensible upgrade, and keep your stockers as spares.
The new centerlink that hoohaa is making looks pretty good. If you're thinking of doing a system, than SLR is a tough alternative. Total Chaos is nice too, but may be overkill for your use. That's your call.
Hope this helps.
