It'd be neat if the Jet variations of the Gomu Gomu attacks were changed to be the instant style of attacks shown most times Gear 2 is used. Visually this'd have the shockwaves appearing at the end of the attacks hitbox and the arms would go invisible. It could also increase the hitbox of the attacks, so Jet Gatling for example would hit any enemy within range of the attack (instead of only enemies who get hit by the fists, so about 2-4 fists per Gatling depending on your luck) or Jet Bazooka, which would be one large impact (stopping enemies from dodging the Bazooka when aiming directly at them)
