The reel has the interesting ability to spin in tight circles while conserving momentum. Attacking in combination with this can make you rapidly accelerate while remaining in a tight circle. This is known as the reel's Overdrive, and it allows you to effectively hover over a titan's before striking and achieve an larger than normal damage. If you have a hook placed correctly, this technique takes away the need to have to position yourself for a strike because reeling takes care of this for you! You can deal a massive amount of damage without ever having to let go of your wire!
The main factor towards the successful use of this technique is where the hook is placed on the titan's neck. It needs to be on the very center of the nape as shown in the picture below:

In order to activate the reel's Overdrive:
1. Place a hook on the exact center of a titan's nape.
2. Gas only in the direction you're traveling.
3. Spam attack and reel in at the same time to accelerate into an Overdrive.
This technique is a direct-hit approach. It can be used independently or in combination with formal techniques such as the Spiral Strike or Yo-Yo.This technique works against all titans and bosses, but it is not suggested for fighting the Colossal Titan. While this works on crawlers, be careful not to get eaten.
FUNFACT:
While overdrive is meant for use on titans, you can overdrive on the ground and accelerate unhindered. In fact, you can accelerate so fast that you can break through walls and barriers. That means you can Overdrive to escape maps! - FIXED
