Finally hit 1600 in Voobly. How to get 1700 and beyond?

I was a 1700 HD player 4 months ago. I thought everybody was exaggerating the difference in ELO between the two platforms (and maybe they were a bit), but I'd say that based on my experience there's a 300 point difference between the two. I've finally worked my way up to 1600 after dropping down to 1450 when I first installed Voobly.

I've gotten a lot better in the last 4 months by forcing myself to play more aggressive and playing with better players. What's your tips for getting past the 1600 hump?
