<<Emphasis added.>> Actually, that's not the case. The most popular traditional intermediate blades are the Wilson Coronation Ace and the MK Pro, both with 7' main rockers. The Eclipse Aurora (440C stainless steel, nominally comparable to the Coronation Ace, but actually has a flatter spin rocker) also has a 7' main rocker. The original Ultima Legacy had a 8' main rocker; it has been rebranded as the Legacy 8. The Legacy 7 has a 7' main rocker. If you are considering the Paramount CA or CP, you should confirm directly with Paramount what the main rocker radius is. Paramount says that CA is comparable to Coronation Ace and CP is comparable to Pro, but Paramount is mainly concerned with spin rocker profile and toepick configuration; they don't think the main rocker radius is all that critical, and their website is vague about what the main rocker radius is for those two models. If the Paramounts indeed have 8' main rockers, those would be options for you. Before you go the Paramount route, though, make sure there are sharpeners near you who can sharpen Paramounts (not all skate holders can handle the thick aluminum chassis). A final option is the Wilson Coronation Comet, which has an 8.5' main rocker. It's no longer listed on the Wilson website, but major online retailers still list a full range of sizes.But I'm still not on high level, I just started learning some singles. Is it okay for me to overblade to advanced level blades? Because I think I can't adapt well with different main rocker (7' in this case), while most intermediate level blades have 8' main rocker.
