I feel the same, the lower the class, the more rules to keep it fair, honest and most importantly, inexpensive. That is the only way IMHO to keep newcomers coming into the sport, to ensure the class for years to come.
Look at what happened in the 80's when the OE's started throwing money into the sport to dominate. It absolutely killed the series. You had to have factory backing or you were racing your heart out to even make tenth place. Few newcomers would even try to enter.
The guys starting out with no sponsors(and no money) need to have a level playing field to keep the guys who are "sandbagging" with the honed skills and with the dollars, out of dominating the lower classes.
As the levels of comp elevate, of course more money can be put into hulls, gear and motors.
Hense the "PRO" classes, essentially in most other classes is "run what you brung, and hope you brung enough." I think the least amount of rules possible, mainly to keep it safe. The classes most EVERYONE wants to see. The dudes(and gals) with the serious skill(and serious money) to be able to(afford to) run a 20K one-of-a-kind hull onto the beach and not even think twice about it, just to make an impression.
Top fuel drag racing, Nascar, Indy, all top classes, all with few rules compared to the lower
classes. Engineered to be the best-of-the-best competing against each other.
Seriously, what is the purse(if any) to win freestyle comp? Lenzi flys himself and usually two to three other people with him from Brazil just to compete.
Doubtful there is any money in winning, the most is the prestige and bragging rights that come from being the champ.
My two worthless pennies.
