Another thing to consider is the weight per gallon difference between rimguard and anti-freeze. If you have larger diameter tires that starts adding up very quickly. I to like cast/steel wheel weights but comparing what can be put on the rim and what I can put in the tire, the rimguard blows it out of the water. In my case, the rimguard still is not enough though. RaydaKub made a great point about taking load off of the front axle. A counterweight is a great thing to have, but sometimes having a single purpose implement or not the right one for what you need doesn't really help much. I try and have my counterweight on when I'm playing in clay because its so heavy. But sometimes it sure is nice to rough it in with the bucket, and smooth it out with the box blade and If I have to constantly switch implements it gets to be a pain. Giving up that 1klbs weight difference between the two is very noticeable though!
