I don't like any of the Giant Dragon products because they are too expensive. It kills the reason to look for a cheap alternative when similar european rubber is available at discounted prices. I remember investigating the Karate Hard before and 1) Giant Dragon products are hard to find compared to DHS/729 2) The price is laughable when for extra fiver you can get a Bluefire or even Accuda/Nimbus/Aurus/Rhyzm for the same price
They seem to be based in Spain or something judging by their official website, which can explain the higher prices for the market they are targeting.
