@ decoherence - I did look at all of the threads you point out and there are some really fantastic solutions, but I wanted something that was fast and effective, not to mention cheap. I believe you are correct about the 2-point system being the best.
With my solution there is some flex, but just a little. I did an experiment for only like 50ft, where I loosened the tensioner bolts a little and it held. At this point, I've only put about 15 miles on my rig and all looks good.
My biggest concern, and I should have stated this in my original post, is that over time the engine torque and tensioner will win out. Regular PMCS (Preventive Maintenance Checks and Service) should catch this beforehand.
Any other advice you can provide is welcomed. After all, I am a noob
