I just replaced the slings on my Star Trek Pro with orange rings from Titan (thanks to ectobar for the color idea). I have to say that they look awesome! Way better in person. Here are some old pics:
And, here are the new pics:
What was amazing was that when I took off the old black rings, my hands were stained. I thought I had touched grease. They must have been filthy. I love the way the new slings work.
Also, shout out to Titan. Awesome customer service and fast response time.
My next project is to replace the white rings in my Special Force with yellow. I'll post more pics when I do that.
