Bilstein dead horse

Okay guys I'm about to start ordering parts to fix my truck, but cannot sway myself one way or another. I've pretty much narrowed it down to the 5100/dakar kit or 6112/5160 kit.
I know the differences between the two and as far as my needs go, I don't do anything extreme. Mild to moderate fire roads or trails. I do enjoy driving a little spirited on the washboard or gravel fire roads. I don't rock crawl and it seems pavement 90 percent of the time.
Would I be better off with the 5100s and using the remainder to put towards sliders or going for the 6112s.
