This is why I bought the Synergy -- so that I don't have to deal with it breaking. My factory tie rod was bent and straightened a few times and I've seen them get broken. The Synergy is not that expensive and I've never heard of one getting broken. They get bent a bit, but not like the factory rod. Not enough to need straightening.
If you're willing to carry a spare with you, sure it's free. I'd just rather have the piece of mind that it's not going to break.
I don't know, $325 still seems like a LOT of coin to me especially for something that will still bend. I've run an RK tie rod and while it did cost a tiny bit more, I never had it bend on me. Of course, I've also run the more expensive Currie as well and can tell you that it never bent either.
While I have broken more than one factory tie-rod over the last 7+ years, it was never to the point where I couldn't trail fix it and get off the trail. I work from home and so all 70,000 miles on my Rubicat have been put heading out places like the Rubicon or the JK-Experience, wheeling it hard and then driving it back home and all of them have been done with the original factory tie-rod. When it comes time to replace it and I have no doubts it'll need to be replaced someday, I personally would prefer to spend $300+ on something that I know isn't going to bend. But, that's just me.
