Discuss light weight issues concerning road bikes & parts.
I don't think it'd be an issue. The J&L axles (recommended) i've got seem way stronger than they need to be. The axles don't actually need to be all that strong for day to day use. Most of the strength is there to ensure you can twist stuck threads from the other side, be durable while living with all the strains, and to make the system rigid. Most of the weight savings is done by removing features and machining the bolt down more. A bad axle would likely be obviously machined poorly or keep loosening up on you, so you'd probably be OK trying axles out.
