Your belt pile looks just like the belt pile I've had mid season for 30 years. If I can get 200 miles out of belt in the Nevada heat it's a miracle. I tried every aftermarket belt ever made and found OEM is best until I discovered the Gates Carbon Series. I've been running a 44C4553 on my 2014 for about 800 miles. I broke it in properly, always give it a decent warmup before flying down the trail at 80MPH. I don't even look at my belt anymore throughout the course of the day, just ride. Some claim they blow into a million pieces at a moments notice, I've had nothing but great results with zero heat fade. Highly recommend!!!
