UW Blade never really has Gas Problems, especially after the printing of Snapcaster. Bobs and Vindicates also mean less Flashbackable-Spells being played in the deck, making Snapcaster weaker. UW Blade has been the steadiest deck I've played in a long time. It has very few weak Matchups and is pretty much even across the board against most decks. The strength of Colourless lands like Mishra's and Riptide cannot be underestimated. I might even risk saying Factory + SOFF combo or Snapcaster + Riptide ->>> Black splash.
UWB will make the deck slightly better in the control mirror and will give it more options against combo. However, it weakens the overall durability of the deck and makes it easier to be picked apart by RUG Tempo, Old School Team America and Disruptive decks like Aggro Loam.
