It is like difference between Voltric Z Force and Voltric Z Force Olympic Edition... any difference? Maybe not except for paintjob... Kason F9 LTD also released for Olympic 2012... correct me if I'm wrong.
As mentioned, the difference only maybe in the paintjob... spec should be similar. However, if you are refering to F9 and F9 PT, then there are differences in spec
Not only that, it also has 5 stars at one side of the T-joint and some chinese wordings on the middle of the shaft http://www.e1981.com/Sports/ALCE277.1.html
