These look interesting.
I like the TKC70 rear, but the first tire, while good traction, has created problems for me the last two tires I have had on the bike. The previous one cracked longitudinally around the centre of the tire and its replacement, currently on the bike, is not of a regular shape. The wheel is balanced but it bounces because of a small difference of radius at one point!
I might try the Mitas on the front next time.
On Red, I have the Avon trekrider on the rear and I do like it. Was thinking of putting the TKC 80 on the front, but might try this tire on the front.
