bunkers edge board with handles

the board i always see next to photos of bunker intrigues me – would a 4" thick edge board with rail handles work? be interesting to give one a whirl. any comments? thoughts?

I think the other photo is a better indication of how it works. He is pulling with all of his might on the handle and hanging his ass out over the inside edge an yet the board is barely banked…conclusion; it went very fast in a straight line and took herculean effort to turn which is why, nowadays, no one rides 4-inch thick, resin-bead-sharp, block downrailers with no rocker and handles…
