I replace the front brakes on my Hillborne with the 720s a while back in an attempt to eliminate loud squealing I was getting with Tekro Oryxes. I got the squeal squelched but I find the braking power somewhat less than the Oryx, which doesn't make sense, as everything I've heard gives wide profile, high straddle wire cantis more advantage over the narrower ones. It's not a huge difference, but it definitely resulted in somewhat less stopping power. I am so happy to be rid of the squeal/ honking and so weary from swapping pads that I dare not mess with it any further. I personally like the look of the Oryx brakes much much better.
