Hi,
i want to change my blade, actually i am using Yasaka Sweden Extra. I want something faster. I want to use Xiom Omega VII Euro rubbers. Thank you for your advices.
Go for Viscaria.
It seems to me the other recommendations are mostly just for whatever fast blades ppl like but that's not taking into consideration what you're using, I think.
If you go for Viscaria you'll have an amazing blade that nearly all the pros use, but more importantly, it will be close in feeling to what you have now. Reason being, the outer ply of a blade is VERY influential on how it feels. Viscaria, like the YSW has a hard outer ply.
Also, I have both viscaria and YSW and tried them with similar rubbers and I can tell you that they feel similar except the Viscaria is faster and a lot more stable.
Another much cheaper option (but very interesting and one of the best new blades) is DHS301, which is an innerforce type blade with a hard outer ply (koto, like viscaria).
The YSE feels quite different to most other 5ply blades. Ppl who haven't used it won't know. It's very, very solid feeling. With hard rubbers it's even very fast, but loses a lot of the ease of spin. The Viscaria actually feels a little LESS 'solid' and spins easier.
