Advice on new blade

[NetProphet]

Hi folks
I'm seeking advice on what blade to try next in the hope of avoiding any expensive mistakes!
I have been playing a Yasaka Silverline All Wood since returning to TT 2 yrs ago.
It's a relatively slow blade but has great feel and has been brilliant in helping me to build my strokes and techniques. I'm still looping everything on both sides with Rakza X Soft on BH and Rakza Z on FH.
I don't want to move to carbon or anything too fast so what I'm looking for is another All Wood blade that is a bit faster but will retain that all important feel and feedback in the hand. Hopefully this blade will then allow my technique to take me to faster rubbers than I have currently and thereby (hopefully) a more dangerous player.
I'm tempted by the Nittaku Acoustic or Violin but I have trouble believing they would be worth that price to a player at my standard, or maybe they would be?.....
Be delighted to hear your feedback on them or other blades you might suggest!
Thanks in advance
Andrew
