I have a couple of these blades and I play (currently) DHS H3 Neo 39degrees on both FH and BH. I also have these rubbers on other blades. I would go back to the basics: Do you want a hard or a soft top wood? Are you a Limba, Walnut, Hinoki, or Koto person? Then look at the speed table (
at this link). I feel that it gives a good impression of the overall speed of the blade (minus the soft to hard difference of the top layer).
Specifically:
* Fextra 7: Two top Limba layers, very jumpy and fast (1400Hz). Harder to control than the slower blades.
* Yinhe 537: Top Walnut over Limba (1400Hz), and thick. Good control but heavier blade.
* Yinhe 437: Limba/Ayous (1400Hz). Softer than 537.
When you order a 537 or 437 you may get the "S" (later) version which is slower (e.g. my 437S is 1270Hz).
* DHS Fang Bo 2: ALC inner, Limba top, plays very nicely, 1320Hz.
* DHS Fanb Bo 2X: Same but faster (>1400Hz), thicker core, similar weight.
* Yinhe Pro 01 or 05: Koto or Limba top, external or internal carbon-containing layer, 1485 or 1356Hz.
So there are lots of options in the sub $50 space. Handle shapes are also different so I would test-drive the blade before buying or just buy it and give it away if you don't like it.
For all wood blades I like the Yinhe U1 VB (no longer in production) which is a slower 7-ply Limba top blade.
Due to technical difficulties I actually play the Victas Swat which is my slowest blade (thin, soft 7-ply Limba/Ayous top) in tournaments.
