Bob, I asked the same question quite some time ago:(posted 8271 days ago)"The only trace of Paterson's new ascorbic-based FX-50 here in the US has been brief mention in Photokina reports. A visit to the Jessops site shows current UK retail availability. Has anyone over there tried it, and, if so, would you please share your results? My fantasy has FX-50 as an Xtol equivalent that performs consistently. Hope springs eternal! Thanks in advance.

No one ever posted any experiences with the product. I've since "discovered" Ilfosol-S, and find that it reliably provides Xtol-like results.
