Everyone is praising Havoc for being a consistent org all round but when I had my fighter there i found that org to be a highly disorganized mess with bad communication and i couldn't leave that org quick enough.
But that was at the beginning of the year and from what i have seen (i have spoke to Davie about this as well) they have made massive changes and i am actually thinking about signing a guy there once his current contract finishes because they seem to have seen where they went wrong in the beginning and learned from them. I put it down to being inexperienced and i look forward to seeing the new and improved Havoc when i re-sign there
However King of the Beach gets my vote. I signed there to help Octagon out when he was still relatively new to a low contract despite being in Rio. While i was there, i found him to be very effective from day 1 in his communication skills and his interactions with his fighters. So i signed to help out with a short term deal, and i re-signed because i loved the org. Hopefully he can keep it up!
