i use the Spearco 29.5 x 12 x 3 on my RST and it works great, i have been happy with it and i have no reason to change... personally i thing the Greddy IC's are way overpriced! i am happy enough with the Spearco that i think i am goin to get another one for my GST... i like the 33.5 x 12 x 3 (HUGE!!!!)
