Not disparaging what you say, they are a breakthrough, but also remember that they are far from new.
Youngblood uncovered the original Bridge patent that dated back to the 1800s I believe. Grizz even made one from the patent plans. The original used four posts instead of spreader bars though. For those who complain about the weight of the Bridge spreader bars, think about carrying those four posts !!! :scared:
It's amazing how long the breakthrough languished before being picked up here on the forums. :scared::D
