Durablue is good. Lonestar is good. They will guarantee them and fix them one time for free if you bend it. But depending on your riding style the rpm dominator 2 is the way to go. They are lifetime guaranteed against bending or breaking and they will pay shipping both ways in almost every case i have needed them. Hands down best axle on the market. So far i havent bent or broken one but they did send me some wrong pieces by accident and paid all the shipping and overnighted the right stuff to me. Most anyone you talk to will tell you there axles are bullet proof.
