i have the Shinko Advance.. got them from the pony.. the rear is not as round as other tires, but for the riding im gonna be doing this year, alto of commuting back and fourth to work, long trips, i think these will do me well. i looked at alot of reveiws, and its about 50/50 soem guys love them, other hate them most people who hate them either 1. never tried them or 2. are people who ride track days ALOT. i havent really got to get into the tires yet, but the little riding i did on them they were great, seem to heat up decently quick, and the grip was pretty good. will i go with a different tire next year?? i dunno we will see how these pan out, and if i decide to get a little more aggressive with my riding style. found this info out as well.. shinko sided with yokohama and obtained their tread molds as well as the same materials used
