Several hundred twine tied a year here and I don't really see much difference when compared to net or wrapped.

I would not rent mine out to another driver though. A fairly popular builder is not far from me and the number one issue they see is people loading them down and messing the axles up in mud and field entrances. Cutting a corner and hitting a tube with a load on is really easy to do in hay country here. Our roads are horse trails compared to other areas though, so maybe it wouldn't be an issue.
