Now this is just my opinion dogtown. You can't make a solid roll like a true pearl and vice versa. 811A is a shiny pearl, that really clears the front. 912T 1500 abralon solid that reads early and hooks when they are super fresh. 811C/T from what I have gathered (haven't thrown it yet) is a hybrid cover that will read quicker than the 811A but cleaner than the 912T. This is the first ball that isn't shiny without having a "T" on it. Something I feel that is missing in Track's lineup. Track has made too many OOB shiny balls. I really feel this is really rounding out their 2012/2013 lineup so far. 300A, 503T, 706A, 912T, and 811C/T.
