Do some searching on this site and a lot of reading. I would personally go a lot bigger. If you have the room then UPGRADE at least 125 or more. I made the same mistake. I started with a 30 went to a 60 flat hex, and now have a 100 60" long. I would go bigger, but I do not have the room. I would love a 150 or bigger some day or even a 180. I know it sounds big, but you will be a lot happier in the long run.
