I am a intermediate player, i still dont have a main focus of playstyle
This doesn't particularly sound like an intermediate player to me. Maybe instead of changing equipment, your next step should be strategic -- thinking about your strengths and weaknesses and trying to develop a coherent playing style. Develop some serve-and-third-ball combinations, maybe even some fifth-ball combinations and rally strategies as well. How long have you been playing?
I think a good benchmark (in terms of skill) for what most people consider an "intermediate player" is being able to consistently loop long pushes. In terms of tactics, most intermediate players are familiar with their strengths and weaknesses, and have started to develop combinations and rally strategies that are built around their particular strengths and weaknesses.
I currently use yasaka sweden extra with dignics 09c as my fh and fast arc g1 on my bh. Im planning to change my set up to a carbon blade which is DHS Fang Bo B2. I also plan on changing my FH to vega europe.
This is a very odd equipment setup. What is your logic here? You have very fast rubbers on a very slow blade, and then you want to change to very slow rubbers on a very fast blade. I'd say you should stay with your current setup compared to the switch you have proposed. Vega Europe is a beginner rubber (a pretty bad one imo) and it will not help you in the power department.
If you want to improve speed, you could use the same rubbers on a faster blade. You could also work on improving your technique so you can hit the ball harder. I would really recommend against switching to Vega Europe.
is there more better options price and performance wise
Price-wise, rubbers like Hurricane 3 Neo or Jupiter 3 or Battle 2 or the Rxton Pro series would be your best bet. Hurricane 3 is, of course, the gold standard for a high-quality cost-effective rubber (on forehand at least). Battle 2 makes for a good backhand rubber. Jupiter 3 is more of a hybrid rubber, more like D09c. As an intermediate player myself, I think it's much better to use these rubbers instead of spending an arm and a leg on D09c. I'm not good enough to notice what I'm missing from D09c. Save D09c for when you get a rating of 2000+ .
