Just out of interest I tried looking for 5 line bars and they are rare! You may end up having to rig one up yourself. If so any of the bazillion used 2014 slingshot bars from real are a great bar to adapt. It has all the right parts and really just needs a 5th line.... which Slingshot sell.
Again, If you need help setting it up. Lean on your buddies, but should all else fail PM me. Setting one up is only a small pain in the ass, but you for sure know the why and how of your bar by the end. Especially trimming...... thats gold. Welcome to kiting.... embrace your inner nerd.
