I love my 3 sets of Berd spoked wheels and highly recommend them for many applications. That said, for my big hitting bike I choose to go with standard steel spokes for the rear. Berd spokes tend to feel a fair bit looser at times and also seem to get a bit sacked out with use. And I'm no Pro. Wouldn't have anything but Berds on my Trail/ XC bikes, but for a DH bike, I'd choose otherwise. If I had to build a new AM/ Enduro wheel set not certain what I'd do. Probably Berds though.
