Mono, totally not my game, but would think less shock worthy due to more of an immediate stop of force in 1st HH, backed by 2nd.
>>looking i think for dissipating shock thru dispersed travel and then perhaps some thru seating coosh/mattress of stack?
Maybe some mattress padding in stack being innie Bunt Line rather than 2 HH's outie form type dampening,
but not so much continuing forceFlow past the first nip/stop of HH.
But, SEEMS to me, Davey offers longer fig8'ish travel thru gauntlet of bends before total termination of force flow?
AND softer 'mattress' dampening of stack than before standing as fig8 rather than flatter HH stack?
.
mono many ways different than working ropes.
