Hey if you want to get serious about something that looks good go with Hangar 9 pro Linkages or carbon fiber pushrods. That is what the pro's use. I have HAngar 9 linkages on my 37% Ultimate and CF Pushrod setups on my pattern planes. What is nice about the hangar 9 linkage is that its threaded so that you can adjust the length of the pushrod just by turning it. Then you tighten down the locknut against the ball link or clevis and you are locked in. You dont have to take things down to make adjustments. They are a little pricey but very clean.

Here are some links to the good stuff that we use on high end airplanes.
