Personally, I love the Wednesdays-Sundays format (even though it's all but killed the tabletop I used to go to). Really, my biggest concern is ye refs having enough time to work your refly magic on all the chaos that happens without your sanity going AWOL. If you can, and it's working out, then a) Awesome, you rock; b) Squee, bi-weekly ShatLeg! :D
