Last 3 months I run DH22 on both ends... yeah 3009g kombo is bit on a heavy side ale asphalt rolling resistance is close to the army tank, but oh man... these are pure grip monsters everywhere! love them... waiting for DH34 for the rear to make it bit faster uphiller... definitelly recommend for every day ride... your legs will grow visibly each pedal stroke and you will be rocket uphill on some average tyres later on :-D
I've just started running 22s front and rear, no tyre inserts but they are on enve m730s with the integrated rim strip. Im running softer pressures than i ever have, laughing off square edge hits, plowing and brapping where I'd usually be stressing. All round grip level is insane, reminds me of the old FRO intense tyres. Pretty bloody impressive...
