I am comfortable enough with hack rigs, to ride anywhere solo, or with my monkey. The handling is different for load or no load, but it isn't scary - to get a rig to do anything frightening, you first have to do something you should not be doing - like speeding into curves, as you can with a two wheel bike. If you understand the limitations of the hack machine, it won't surprise you, scare you, or even let you down. There is no intentional ballast in my rig, but I have a jack, a tool roll, a rope puller, some emergency gear, a few spares, and all the Ural tools and gear in the trunk. A total of about forty pounds, and that stays in the rig all the time. I have ridden both one wheel and two wheel drive rigs - I prefer the two wheel drive for the activities I enjoy doing, and the fact that it is a more stable ride in corners - the one wheel drive was more willing to lift, but still was not scary at all. I live in WA, where the roads don't follow straight lines so curves are commonplace, so riding the rig is a sedate meander through the countryside, unless you want to have a pro monkey and throw yourself around in the seat. Then you CAN get amazing maneuverability with these machines and a fantastic work out at the same time. Unfortunately the Pro Monkey I know is not in my family, so the chance of having curvey fun is limited to the experience of my spousal monkey. She does well enough for us.
