Fast rolling 29x2.6 or 29+ tires

So on my RSD sergeant I’m currently running DHF 2.6 in the front and an another DHR 2.5 in the rear ( the original 2.6 blew up with an air compressor ). The tires aren’t bad it’s just way too much for the type riding I like. Like I said in past post I’m mostly in to long distance backcountry exploratory xc bikepacking type riding. While the DHF tires definitely have grip and traction for days I feel like I they are holding me back. However I’m on a hardtail so I still want at least a 2.6 for comfort on long days. What I’m looking is a (somewhat) aggressive 29x2.8 or 3.0 in the front and a fast rolling 29x2.8 or 2.6 in the rear. So do any of y’all have any recommends. Also I live in the Memphis TN area with frequent trips in central and northwest Arkansas
