without getting into a thread like this or this I wanted to see if getting a new stem is the right answer for my current issue.

I am slowly coming to the realization that a great deal notwithstanding, the super pista I picked up is a tad to small at 51cm (53 or 55cm would be ideal) My San Jose was 52cm and I thought it would be ok. The only thing that bothers me about the bike are the drops being much to low for my liking. I was hoping to find a positive rise stem (didn't want to have to flip one upside-down) to put some bullhorns thereby elevating my riding position. I have not found anything that fits that need. Any suggestions before I contemplate selling the frame and picking up a new one?
