Thats a very good question. I hope we are planning on downsizing them, but the problem might be that we can't get smaller ones on island. For the second question, its 1"-1", 1/8" wall aluminium (welded together).

Thanks, I liked the spiral wrap too, its a lot better than the last two years where a cable actually got severed in the chains. And the tensioners was another thing I was hoping to doing. I had a plan for this and was wondering if it would be a good idea. I was thinking about putting a piece of HDPE between the chains, so the chains cut it until the rollers touch, keeping it from being cut any more. Once the rollers touch, the chain should slip on the HDPE, but still be tight from the pressure upwards. So if you or anyone else could tell me if this is a good or bad idea, that would be great.
Thanks again,
