to be fair 20 charges is nothing, especially over 4 months. thats roughly four race meets for me..
My ib's have been pleantyful in power, but have become more and more sensitive to charging and heat changes. After about 9 months of racing they are finally wearing down (the power is still there, but lack of duration) My old GP's did two seasons of racing, so i'm abit dissopointed.. but for the performance i've had im happy with them.
I'm unsure what i'll be using for outdoors.. what ever is cheapest at the time i suppose!
