Tight-Rope is one of my favorite yaoi I have read. It has some good gang action. The most lovely part it's the romance I love how both the main characters would do anything for each other even if it means hurting themselves or putting their own life at risk. I wish the manga would have been longer. There's also an OVA with2 episodes^^. I recommend watching it.
Enjoyment:
After reading the first chapter you will want more of the manga. It keeps the plot interesting.
Overall:
If your planning to read Tight-Rope this manga wont disappoint you !^^ Enjoy(:
