There’s too many choices!!!
Main difference seems to be sponge type and hardness, factory tuned etc
DHS have different sponges - porous, non-porous, sealed with a layer of glue/booster?? Etc
There are also differences in quality ?? Standard, Provincial and National, Not sure if there are differences in pimple structure to the top sheets ???
Nittaku seem to have an agreement with DHS to use the H3 top sheet, they then put the top sheet on their own sponges, I think they have 3 or so versions, Hurricane Pro 3 turbo orange, Hurricane Pro 3 turbo blue, Hurricane 3 Neo.
H3 (standard) sponge made for speed glue ???
H3 Neo sponge made for boosting ??? ( standard H3 boosts well to )
Each version players slightly differently, and can be way different when boosted.
