I’m curious as well, I thought the liberty was the same paterna as the miken pro series, worth legit line, with the same leather as the Rawlings gamer/xle, the pull strap is what is holding me back from trying
So I bought the 13" Liberty, and used it this weekend and was pleasantly surprised with it.
I ran some warm water over it, hit it a few dozen times with the mallet and used it in 4 games on Sunday. The leather is much softer than my HOH (which was expected as its a lower grade of leather), but it is breaking in quickly and the pocket is definitely deeper than my HOH.
I agree with @jkwoody22 that the pull strap is kind of lame, but it's easy to get past.
