Energy trading

Anyone know if the salaries are higher for energy traders at traditional oil and natural gas companies (Exxon, BP, Shell, etc.) versus being at an energy division of a major bank?

I just had an interview with Shell for their shell energy trader development program. From my understanding, the rotation is among risk, origination and operation. You do not actually get to be a trader...

Does anyone know more about this program and if its possible to work toward becoming a trader?

I see that this topic has been touched on before but...I currently have a commodities trading related offer from one of the large energy/oil companies and with one of the large banks which has faired well thus far. I'd prefer to go with the bank which offers better compensation and a greater range in opportunities but with things so shaky right now, are the benefits of Wall Street worth the risk? Maybe this isn't the best time to be betting my future on an industry in distress right now if I don't have to. I’m not looking for a miracle answer here, but if anyone has an opinion I'd be interested in hearing it.
