Zoo!, Adamant, Echo, GU and Czar are amongst the biggest selling brands in the trials world, they're all (nearly) the same thing, just with different names on, so design and manufacture costs will be greatly reduced across the ranges and they will all be very profitable. Having one person owning about half the market, i'm sure that he's doing well for himself. The more brands you have, the greater your chance of selling the stuff! I think he's just greedy.
