Came here to say this. I’ve been using DHFs up front for probably close to 15 years now and the only tire with more grip is the Magic Mary, and that depends on the conditions. There simply isn’t a significant flaw in DHFs at any lean angle. They will not let you down.👍
I have a Rekon 2.6” that I tried this year up front, just to see if it would work for me. On XC stuff, it worked fine, but on the really steep loamers that I ride as they open up mid-summer, I could feel the Rekon letting go in corners. I put 2.5” WT DHF back on and it was like Velcro in the corners, and with straight on braking. Also, it did not slow me down on climbs or at rolling speeds. Rolling resistance doesn’t matter as much in the front.
As for the rear, I don’t think it’s entirely inappropriate to run that pairing (Rekon in the back, DHF up front). The Rekon does roll well, and traction in the back isn’t near as critical. If your trails aren’t particularly steep, you might appreciate the easier acceleration and speed, but can still count on the traction up front to keep you out of trouble.
