that man is a skilled cookie so barrel rolls regenerate spin then? how efficiently are they?
Yes, Barrel Rolls (
Atomos) are a regeneration trick. The efficiency is not great but fair.
The half (one-sided) -barrel rolls (
Ticos: from Costa Rica) also regen (although he does not do them on this video) and are easier to learn. The mini-barrel rolls he does (derived from a Colombian move) probably not (but I am not sure).
Watching him do the tricks in slow motion feels like transcendental meditation
