I like gatorskins the best, although I currently run a gatorskin on the back only. I have a 28 on the rear of my everyday wheels and a 23 on my dura ace wheels. I will run a nice conti up front like a 4000 or a 4 seasons. I have used the Refuse, the Rando and the TServ in the past. I didn't care for the ride of the TServs, took them off after like 100 miles. I run the rando's on my san jose but am not a big fan as they feel sluggish and vague. The refuse are ok, I run them on my trek xo1 with my rain wheels.
