When I was working on potentially putting together a raid a while ago, I had decided to go with Suicide Kings with a couple of twists:
1. Everyone got "bumped up" a spot for being on time. That meant that whoever was on top of the list had to be on time just like everyone else, or they might lose their top spot.

2. There was a MS and an OS list. Everyone who had an off spec made a second roll for their OS gear. That helps tremendously, in that people know when they're eligible for an OS item.

3. If no one wants to take a small upgrade item because they want to retain their place on the list, there can be a roll-off for the item. However, an individual can only take one roll off per night (otherwise they have to Suicide), and if someone only takes roll-offs some number of nights/items in a row, they automatically get suicided at the beginning of the next raid.

Another thing you can do is consider moving the loot responsibilities to someone other than yourself. As many folks have mentioned, and you've learned, raid leading is a lot of work. If the loot stress isn't yours (or isn't yours alone), it helps a lot.
