A little tilt might help, or aero bar extensions with a ski/j-bend to then to bring the hands up.
I had an old ritchey base bar and extensions on my last tri bike. They were s-bends like that and aside from being a pain in the ass to mount a BTA hydration setup, my wrists were always cocked forward like that. It strained that tendon and just made riding very uncomfortable. When i went to get fit, the fitter told me he didn’t know why they made those s bend bars in the first place because hardly anyone could get comfortable. And they weren’t particularly aero. Switched to a new base bar with j-bend extensions and immediately it was better.
