How much are the EJ fees?
Not sure how accurate this is, but I was told there is an initial one time "buy in" per club. I've heard this is anywhere from $2000-5000. This could have changed as previously the annual league fees were pretty low, I want to say something like $500 per team, but now they are listed at $2600 for Midgets and $1700 for SQ and PW. They could have increased league fees and gotten rid of the one time fee which makes more sense over time.
Again, not sure if this has changed, but previously you had to play 2 of their showcase tournaments which were not included in the league fee.
I'm basing all of this off of specifics from their website and what I was told 2-3 years ago when our club was exploring the option of joining, so YMMV.
