Oval A900 vs HED Aerobars

Although these two bars look very similar, I’ve been told that the Oval A900 is a stiffer bar and flexs less than the HED aerobar. Does anyone have any experience with these bars that can either confirm or deny.

Thanks…

I have the Al ovals. No problems with them, good hand positions, comfy and the wide center section is great for climbing.

I’ve got the A900 and they don’t flex. Flex is probably due to tightness of bolts on stem and also on 2 bolt vs 4 bolt.
