Yep I agree it's a good place to get good info, but does require a pretty good filter at times.
I'm thinking of casting a concrete ballast with 3 chains hanging out. I have this notion that it should be VERY easy to attach to the 3-point. What if it attaches loosely, for super easy hookup? What are the drawbacks to a ballast that is loose? I suppose if you have to travel with it in 3rd gear that could be a problem, but I don't see that as likely for me.
The biggest problem I see is forgetting its there and backing into stuff with it, so shorter is appealing.
