Alright, cause I used both of the blue and orange for like half year on a malong 3 nittaku, weight 220+, the tackiest on the surface easy fell off if u don't take care well, so the best way you want to determine it, try it.
What style is your play, looping?Counter ? Defense? And what blade are you currently use ? Some rubbers very reliable on kind of blades to use the maximum potential .
Z2 I'm using it right now, don't think to move it, cause after 3 weeks play, the edge Started cracked and little piece of spone fell off , I don't use edge tape. You can search for the duration of it on the internet, not that durable.
I bought the w968 because your post , been 2 months of light play, feels really different of btf fzd sale and v salc, especially far from table, no regrets buying the blade , then I sold my fzd salc.
