Do I bet?

I'm very, very new to Omaha H/L, so feel free to flame if this question is ridiculous. Here's the situation: .25/.50 Omaha H/L. It's heads up and I have the nut high. The board allows for a low. It's checked to me. If I bet and he calls rake will be taken (at this point the pot is below minimum rake requirement). Is it worth it to put in the bet?
