So I'm going over all the options, and all along I've just been assuming ESP is the short center log and SPS gets you three full logs. I read the SPS150 details again and it says three 25" full length pontoons. All along I was thinking the SPS included the 32" center log to give the V hull type ride. It looks like you can't the 32" center log until you go up to a G series? If so this really changes things for me as I can get a better deal on a Harris Flotebote. I was shying away from the Harris Flotebote because their tritoons in my price range all have the same size logs and I was thinking by getting a Benny I would have the large center log like I wanted but now that doesn't seem to be the case.
