BTW, there are always those that claim they can't make a pull-up work, but they're either not creative enough, of are fully incontinent, or have this strange need to flood everything.
4+ years making pullups do the job daily, currently in a high demand, close quarters environment, driving about 6,500 miles every 5-6 days. I'm very creative, and very stealthy!
