  We explore the scale-dependence and correlations of jet substructure
observables to improve upon existing techniques in the identification of highly
Lorentz-boosted objects. Modified observables are designed to remove
correlations from existing theoretically well-understood observables, providing
practical advantages for experimental measurements and searches for new
phenomena. We study such observables in $W$ jet tagging and provide
recommendations for observables based on considerations beyond signal and
background efficiencies.
