I bought a DynaBar rope slider which I haven't tried yet. What if any problems happen if you boost big with a rope slider ( I assume you set yourself for mid air rotation and a water slam)

Ive Noticed that on some of the more recent on line videos that some crew kiting in waves (mostly that Alldredge bloke ) are using a harness with sliding spreader bar with rope ( i think its dyneema or something similar) with a carabiner clip attaching them to their chicken loop rather than the traditional set up . looks like it gives a lot more freedom for manoeuvers. sorry this is probably a **** description

any one using this set up , is it better in waves and as safe as a standard harness chicken loop static spreader bar set up.
