I have made most of the major decisions for what I am looking for and I found a used TF 550 and I would like to get a B410 Neo Avatar cab to go with it. However, I am not sure if I should go with 4 or 8 ohms. I have been reading around here, and most people like the 8 ohm idea better since I could add another later. But I really don't think in the near future I will need much more power than a 4x10 has. I rarely play big gigs and I will be going to college next year, where I probably am not going to have space for a huge speaker setup. How much louder is the 4 ohm vs. the 8 ohm? Right now I am sort of leaning towards the 4 ohm since it will be louder and I don't really see myself adding much more at least for a few years.
