Is anyone familar with GRZ Energy (http://www.grzenergy.com/main). I've seen them on CNBC numerous times and they really sound like they have a pretty good grasp of the energy markets. Has anyone every used their service (its pretty vague on what they do on their website), but it seems that they are simply CTA's and floor brokers in charge of executions. I'm looking for some Energy CTA's/brokers that can help advise me (and do pit executions) for some energy spreads. If anyone has some comments on GRZ, or recomendations on some other CTAs worth looking into it would be much apperciated.
