only improvements i can think of would be a paintball that can be spun more effectively and a marker/ barrel capable of spining it, in order to gain distance, and making what already exist lighter, smaller and more efficient.
either that or too move in a whole new direction (like me)... but what the sport really needs is better, cheaper entry level markers and equipment to make it cheaper and easier for younger people to get into the sport...but the industry is kinda taking care of that anyway (there is still a really big price difference between us and the U.S...even on brittish made stuff)
thats what the sport really needs, but my brains geared towards the new and different.
"I'll come up with the conceptS and leave the japanese to deal with the details"
did someone say that once or did i just make it up, i really dont know?
