I use the 712 rears all the time but don't care for the matching 712 front. It's kinda "squirmy", giving a gentle head shake as I go through about the 35 to 40 MPH range. I guess I've grown used to it because I hardly notice it anymore, but needless to say, I won't be using one again. For a front tire, I like this Metzler style tread pattern .....

It's worked well with any rear I've tried it with. Unfortunately, Cheng Shin stopped making them, lol. But there is another tire manufacturer, Vee Rubber, making copies now .....

And of course, you could always buy the original Metzler if you didn't mind paying an arm and a leg, lol.
