My opinion is that we do not allow Folders to do -bigadv/-hugeadv in the TC anymore, in any positions (neither of the i7s, and not in 2500k/X6 either).
While I realise this would result in a slightly lower PPD for OCN, and wouldn't be the best decision for some TC Folders, I think the influence it can have on the TC is too great now, considering how hard it is to get the WUs. It's more luck than skill at this stage, and it's not something that makes for competitive Folding. Plus, as we're looking at restructuring the i7 positions, going by SMP-only would make things a fair bit easier.
Anyway, I'll put a poll up in a few days, but for now, let's get some discussion going on the matter.
