As a H10 group - Roll, with haggling permitted (e.g. 'I'll pass the first 1h to you if you pass the second to me' or 'this isn't my preferred off-tier piece but it is yours, so i'll pass to you')
I believe our other H10 is using loot council currently, although they might just be using roll too.
We were a H25 guild prior to MoP & used a slightly unusual implementation of EPGP (33% decay & and EP per raid hour being the main features). It worked well as an egalitarian distribution system. We'd been through a lot of variations of DKP/EPGP since TBC and found that one to be best.
When we shift to mythic, we'll either swap back to the EPGP system or we'll swap to a loot council system (one that includes a player created wish-list). We haven't decided if we want to go with the egalitarianism of EPGP or the focused-distribution of loot council yet. There are positives & negatives to both.
