I would say either A or C for myself... was a shoehead back in the day and luckily got out! lol but really want to get the metcon's because cheaper solution to the Roma's.. I can use the Metcons for other exercises and not restricted to the lifts Romas work best on.
Already getting tired of taking off my running shoes to do squats/DL and so close to buying Metcon 1s just for the sake, but hopefully there's a handful of people who have the code and not buying :) ... PM as well if you're willing to send the code!
