Hi, I did install a set a few months back. I got them used so I did the install myself although in retrospect, it wouldn't have costed much more to go new because shipping is not cheap. Yes, I do like them as they give the tires more bite. I've installed 2 per side right now and I've got another pair that I'll install this spring once I've cleaned them up and painted them. I can't tell you about stability except that they do help with the ballasting needs since my boxblade is lighter than a fully loaded ballast box. As for side slope stability, again, I can't tell because the uncomfortable feeling comes from the tilt of the tractor and where the operator sits. That won't change with the addition of wheel weights so while the tractor is probably a little more stable, I wouldn't know. Here is a picture of 2 weights installed.
