As the tension in the chain rises it's need for serious lubrication increases proportionately. Tri-flow and other teflon based lubed may be fine for 140# riders tooling around the park at 10mph, but as a heavy rider who mashes up hills you need something more serious. (consider the source here - I make chain lube).
The problem is that more viscous, higher film strength lubes attract dirt, so you have 2 basic choices. Use a lube/solvent lube and clean and lube often, or use a heavy mineral oil or grease that stays in pretty well and lube less frequently, but dry wipe the chain to keep it reasonably clean.
Open Pros are fine for whatever you can dish out, but it depends on the build. 32 or 36 spokes, with a well executed build will be fine, but obviously you're more likely to bend or dent them than a ballerina. One thing you can do to help yourself is use larger section tires for the same reason that trucks have bigger tires than sports cars. A larger tire will increase rim/ground clearance reducing the chance of rim damage on sharp bumps and will be efficient at lower pressure reducing the stress transmitted to the rim.
