When some of us get temporarily bored, we play around and at least pretend to test many things.
Your SA may have the carbon(ish) pushrod, but we tested the wire one too.
All kinds of mostly gentle flying can be done in the early stages of learning, without the guides. There seems to be only minor risks up until the first time you give hard left rudder, particularly when using that to stop or reverse a strong right piro. The wire pushrod will bow under less 'pushing' load than the carbon one, but they both can be made to bow considerably.
The hard left rudder input will result in a 'mushy' response, and the effect can be that a mild loss of control happens because you don't get what you want exactly when needed.
With a higher helicopter direction of travel induced cross wind, or an actual strong wind from the side, both types of pushrods can begin to vibrate, sometimes with surprising amplitude and frequency. At times, some gyros can misbehave while trying to deal with this.
For gentle flying around in under 10 MPH breezes, I don't think there are any real worries.
Many guys have bought some larger diameter true carbon fiber tubing, to make real good unsupported pushrods. Others make a custom support that attaches to one of the screws on the horizontal fin bracket.
You aren't risking a high-percentage possibility of a crash, as long as you are generally flying around upright and easy, but you should be working towards a solution much sooner than later.
