Yea, I do highly recommend that you venture out of Union. You might be surprised. I think a lot of the hype is from people who have only tried a couple of bindings and brands. Union might seem like the best thing on Earth when you haven't tried other bindings.
I used to think Flows were the best thing ever until I demoed tons of bindings. I still really love them and I will continue to buy them, but they definitely aren't the best binding out there. Well, no binding is actually lol. Just saying that there are other binding that make me just as happy.
