standard cranks tend to be heavier because they have a larger BCD... but if you really want to "upgrade" your crank, go get some older SRAM Red BB30 cranks (I'm assuming your bottom bracket is BB30 but I don't feel like looking it up, you really need to find out first because there are different flavors of press fit bottom brackets). previously used standard cranks tend to be pretty available on fleabay. A lot of people dumped them when the new exogram cranks came out. I got a set of compact red cranks for $200 a year ago, so it's possible to get a good deal.

Another option for you, as mentioned above, is to swap your compact chainrings for a set of mid-compact chainrings. Those are 52x36 and will give you a higher gear selection without requiring a crank swap. praxis makes good aftermarket chainrings, but chainrings alone will run you close to $170. Of course, the hazard with buying used cranks is that the chainrings might be thrashed.
