Putting it in an arena based area would make the damn sport explode.
I know from competing in paintball, we were facing the same damn thing. The NPPL league was growing stagnent and dying off, fewer and fewer new teams were being introduced and the tournaments were getting less and less coverage and sponsorships. Every single one was being held in a field in the middle of no where, and world finals would be held (of all places...) in the middle of nowhere kissimmee. But then a group of execs got together, rethought some rules, started a new league, built an arena in disney and immediately got the new X-Ball tourney televised.... ironically the same year I competed in world finals. They made the sport faster, cutting rounds from 5-10 minutes down to 2-3, shrank the fields, and moved everyone closer to the field with grand stands. Actually made it official looking, even though nothing real essential to the game changed. Just a few rule tweaks and a change of venue. This factor alone is what made the marker industry explode. For the first time in a few years new and amazing air valve designs were released and companies actually started pouring in money.
If you ask me.... this is the exact same damn scenario. A relatively irrellevant sport in todays mindset is able to get a facelift and total turn around overnight. Move WF's to daytona and you have the chance of getting it back to the height of its ESPN televised self back in the early 90s... Making the actual racing area smaller will promote faster races, and all people will get further hyped. Less spread apart, more furious competition. Its a win win situation for everyone except maybe the racer himself.
Eventually youll get a few companies able to grow to the size Westcoast, PJS, and SKat and all the others were.
