I have had very high hook and land ratios on bass with Mustad VC71SNP-SS (old ref. C71SSS) . I used the freshwater version of this hook of this hook that is no longer available. This hook works well for flies because it has a longer shank. I don't remember the exact percentages But I do remember it improved my landing hook to ratio by about 17%. The trick is that you have to strip set the hook like most anglers do in saltwater anglers do. By the way I did not hook any of the fish deep. Most were caught in the corner of the jaw.
That said I don't think it is the best hook for Tenkara because you don't strip with Tenkara
