I've got a chance to get a good deal on TKC70 or TKC80 tires for my Strom. What tires would be best for the MABDR? (Outside of this trip on the MABDR, I ride 80/20 with the 20 being gravel roads). I even thought about mixing it up with a TKC80 front and TKC70 out back. Does anyone have any experience with the new TKC70 Rocks?
