Go to Post I think being successful in FIRST is creating an environment where people can grow, learn, change, and recreate... It's about making an environment where kids feel they can be successful... in whatever discipline they choose. - ColleenShaver [more]

This. In my experience, unless grease splatter is a major concern, open is almost always better, mostly because of weight. For example, running a Toughbox with delrin spacers instead of the usual aluminium enclosure saves over half a pound per robot. We ran them that way, and aside from a little grease getting thrown around, they ran like champs.

You may be a little too worried about stuff getting in the gearbox, and not considering the maintenance and weight benefits. I personally have never seen a gearbox fail from foreign material inside. Usually, binding that you might think was caused by stuff getting caught in the gears is caused by improper grease use.
