Mine is a two log boat. I had thought that I had read a different thread on here where people did not reccomend using the log eyes, as that could put to much stress on them and they could develop cracks. When I had my Wellcrart I used a harness yoke attached to the two U bolts and that worked fine. Maybe I will just do that with the toon. It would be a much cheaper solution.
I read the same thing when I got my first Premier(2 logger) the dealer had said to use the harness on the log eyes. I thought the dealer was a straight shooter but still checked directly with Premier after reading that it was a no-no. Premier said yes hook to the log eyes if its a 2 logger. Dealer was a straight shooter as I thought.
I also highly recommend using a Sports stuff booster ball if towing tubes, it gets the rope out of the water and makes it much easier to sling the tube out of the wake.
