Need tips on doing parlay sheets with players from my fantasy football league (I'd be the bank). Pretty simple - I want to start doing parlay sheets with my fantasy football league but was wondering if that was an awful idea.

I have a decent bankroll and really am looking to do this more for fun than for making money.

Do any of ya'll have any tips or suggestions if I do this?  Maximum bets?  Cut-off times for bets?  When should I release the sheets?  

Any information would be helpful.
