RPOOL for Primecoin update

I have stopped mining on RPOOL. After 16 hours of mining I have not had a single share drop on my status page. I'm not sure if it is RPOOLs miner which I was using a modified version of the Beer pool miner or the way they issue rewards. I decided to go back to Beer pool to finish mining. Besides at 1% fee at Beer vs 2% at RPOOL I feel in the long run it is the better choice.
