latvian gambit maybe? ultra agressive!

if you are looking to roll the dice with an all or nothing attack straight off the mark, probably look at one of the gambit lines.

ok thank you!  I will definitely look up the latvian.  a lot of the gambits take about as much time as anything else, though.  As I'm thinking of this, Marshall Gambit would work for black I suppose.

I forgot to mention the Blackburne Shilling Gambit for black.  I like that a lot.

Perhaps you should rethink your decision to look at changing openings to solve your time management problem. Dan Heisman's Novice Nook column has some good articles that address this issue, one in particular.

As for using the Colle or other system-like opening to save time, that only goes so far. Here on chess.com, with the vast number of novice players, this doesn't help all that much because you don't see mainlines as often as you do against a stronger playing field. So, you'll still be required to think and not play automatically, as the automatic move may not be best and may even be bad. Indeed, picking the Latvian is about as far from a time-saving strategy as I can think of for a novice: the opening is treacherous from about move 3 on. Only someone with a prodigious memory or supersharp tactical skills would want to employ such a strategy - though surely your opponent will be set to thinking.

In summary, knowing an opening will aid in time management, but there is much more to time management than just the opening. And, you can minimize the problem by moving to G/30 instead of G/15.

hmmm I do like traxler but I've never tried it in a blitz game.  I'll have to see how it works!

I'm reading that article now.  thank you!

1.d4 nf6 2.c4 e5 look into it

In blitz, as white play aggressive openings to take advantage of the time control.

As black, play solid openings (1.e4 e5; 1.d4 d5) as you will not use as much time out of the opening.  In addition, you level the playing field with your opponent.
