I am pleasantly surprised how well the Shinko 700 front is doing. The rear 700 wears to fast for my needs but, the front does provide better bite on dirt roads. It goes very well with a rear 705. For the money and performance the 700/705 combo works very well for me.
I have one 705 front left in the shop and after that one, I'll be sticking with the 700 on the front with the 705 on the rear. That way I get a little more stopping power on dirt and I can just change them both every 6,000 miles or so. The front 705's last forever, so on long trips I would still put one on. But, for my usual day rides and short 1,000 mile trips I prefer the Shinko Mullet.
