The Rekon is like the cross country Ikon on steroids, which is pretty much how Maxxis has described it. It's about the easiest tire to "spin up" in that size and it rolls extremely fast... But... I would never expect the Rekon to play in the same product territory as the Minion. The SE4 seems to make it into that discussion frequently. I love the SE4, but there is definitely a weight and rolling resistance penalty.
I don't see where they are that close in weight, though? The DC Rekon is 800 (my rear choice) and the EXO (front choice) is 840. The SE4 weighs in at 905. The 2.6 Rekon EXO+ that I'm trying now is actually lighter than the 2.4 SE4, but I don't have enough miles on it to really say how I like it. And we'll see how long it lasts up here with all the rocks and my less than graceful style- especially the awkwardly landed drops.
