OK firstly about Stall 2, the reason why its so awesome, is because it sets up dual screens, can very easily break stall (unless stall has heatran but thats fixed with a Kyogre), and its near impossible to OHKO (even Specs Kyogre fails to OHKO and can only manage a 2HKO since it will Light Screen before it can Spout, if it runs Sub ogre runs out of pp.)
Sub phaze lugia is -_- I'd think of going with Chansey Lugia core + Stall two to break stall, some kind of Kyogre to break down those annoying Heatran. You'd only need a steel for Dragons and then can select from a wide variety of Specs Ogre switch-ins then.
Abomasnow is pretty "meh". The idea of research week is to encourage new discoveries in Ubers though, hail is anti-meta I guess, but anti-meta sucks.
Since most of the important stuff has already been discovered (ubers is too balanced!), research week will probably end up failing all the time.
Sorry about my inactivity on PO too :(, School has officially become a troll for me.
