“Best” is subjective, and pokes fun at the idea that there can be a single best item for everyone.
But I am nearing completion of a Comparison table for low drag (long tail) harnesses as of 2022, so I share now.

It is taking me more time than expected to complete, as to fill each row of data, I have to read the corresponding website, user manual, related videos, ask some owners and manufacturers.
Hopefully this will be helpful to others. It is probably harder to choose a harness than a wing, with so many factors including personal comfort and feature preferences.

If you are considering a harness (or anything else) for yourself, I will be glad to help you get a discount for any brand or model, just ask by Email.

Good flights, Jerome
