Longboard Help

Good day. I am seeking some help / advice. I am looking to purchase a new longboard. I have being surfing for 8 years - currently an intermediate surfer. I catch a lot of waves - can turn pretty well but don't surf enough to do much once i am up on the wave. I am looking to keep improving and want to get a good board. I live in South Carolina and surf some beach breaks, however, the waves here are normally very small. I go to Costa Rica for one week a year and surf beach breaks. I am looking for a good all around longboard. I have rented a 9 ft McTavish Original several times and enjoyed it. I also rented a Robert August (I think it was What I Ride but not positive) and enjoyed it as well. Someone recommended a Bing board. I have looked at the Bing website, however, they seem geared towards nose riding. Not sure if they make a good all around board. I have not surfed the McTavish Fireball Evo II - that seems to have replaced the Original I surfed. Any advice on several good boards to consider? Thanks very much.
