The 2 pvc pipes way also gives you more flexibility on how you can use the straps bar, like you can do one hand on the pvc/straps and one off, on the fabric wrist guard that is around the bar, w/o straps on that wrist, etc. Plus, the two pvc pipes does make it closer to how it is on the real bars, and you can shift where each hand is on the bars - but not with the one pvc pipe way.
