Okay, just to clear it up:
- The first release is a pretty cheap one. Until you hold down the fire button, it applies force to you in the direction of the grapple point. When you release fire, it does the same, but with more power.
- The second release is a terrible mess and should be forgotten.
- The third release is what actually the second was supposed to be. It doesn't affect you at all if you're closer to the center than you were at the moment of the grappling (because the rope is 'slack'). When holding fire down, it tries to keep you on a circular path. The redius of that path is constant (the distance at the time of grappling). Releasing fire reduces the rope's length and applies more force towards the center. The speed of reeling in is constant.
Of course you can always add to your speed by jetting. The old grappler though (first release) could increase your speed all by itself. The only problem with the new one (third release) is compensating the effects of gravity without slowing down radial movement.
