On a "You showed me yours, allow me to show ya mine" note... I am in one $$ FF league that has to be the most complex, insane FF league ever. It's also my favorite league, for those exact reasons.

* 20-teams, with 16 of the owners ranked in the top-250 overall on ESPN
* 40 roster slots (21 active, 19 bench) plus 4 IR slots
* Full IDP
* Can start 2 QBs
* 15 category roto, not h2h. Categories are pass yds, pass avg, rush yds, rush avg, rec yds, rec avg, return yds, return avg, points, tackles, tackles for loss, sacks, fumbles forced, interceptions, passes defensed.
* Full dynasty (you keep all players on roster from season to season)
* Annual rookie draft (by email...takes about a week)
* Annual UDFA draft
* Unlimited trading, both of players and present/future draft picks (and an insane amount of trades...we had 37 individual trades made during our rookie draft this year)
