U-turn isn't very useful on archeops seeing as it's pretty difficult to get him in safely and once you have, you want to do as much damage as possible with its good coverage. I don't think LO would be such a bad idea, though, as once your flight gem is gone, archeops really suffers from lack of a boosting item to nab its OHKOes which it really needs considering its frailty.
@molk, crawdaunt is very dangerous, but I wouldn't say it's a good cleaner, it's main flaw IMO is that it is still easy to out-speed even at +1 and that hampers it seeing how hard it can be to set up. Personally, I like lum berry>leftovers. You won't really be doing anything with crawdaunt's mediocre bulk anyway and lum is just really nice for being able to fearlessly switch in on things like slowking and dusknoir without fearing burns that will render crawdaunt useless. It's also very funny if you're fighting CP sigliyph and you set up a sub after curing the burn and watch them do nothing, even at +6, +6 :P
