I think it must be similary than nbg 95 with less power and a lil bit more durability..
Finally i see Ti10 in YY badminton rackets chart. I presume the Ti10 indicated in the chart is Ti10 (3rd gen). Am i right?
In terms of head heaviness, ti-10 (assuming 3rd gen) should not be up there. Its pretty head light, should be even head lighter than the Arc10.
