Team Impulse Top/Mid or Team Dig Top/Mid?

Right now I've got Impact and Xiaoweixiao in my roster, with Gamsu in reserves, and ability to make a trade for other Dig players. This week in my league we're all even so it's highly important xD. I'm worried that last time Impulse got beat by Dig, but I don't know if Dig are still looking as strong as they did earlier.

I'm kinda thinking of leaving my trust with Impulse, both teams face fairly easy teams in their other games.

Any thoughts?
