I have the mini champ and I can say it is not that heavy. But, it has some duplication, and a (to me) useless tool, the cuticle pusher. The Classic is to "empty" for my tastes.
If you prefer a lighter, I will second the recommendations of the other members to go with a Manager or Rambler. The Alox versions are thinner and lighter, but do miss out on the toothpick and tweezers. Depending on your enviroment, you might need them. The MiniChamp has a pen, and I need a pen handy, so that was an obvious choice, and I do find the use for the other tools.
