Not tried the nukeproofs but have tried both the Race face ambush (d30) and the Race face dig ( hard shell). Sold the Ambush as with the movement of cycling the lower end of the d30 pad used to bunch up and then harden under the pressure before trying to wear a hole in my shin. All in all I found the Digs a lot more comfortable and they are my preferred option.
Other option I’ve tried and stuck with is the G-form. You need to measure up properly to get he right size and they are a lot longer than the standard pads essentially coming up like legwarmers with protection but they work fine both when on and suddenly off the bike.
